Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to transition metal catalysts for aromatic or vinylic C—O, C—N, and C—C bond formation, and more particularly to transition metal catalysts for aromatic or vinylic C—O, C—N, and C—C bond formation that include ferrocenyl ligands and a transition metal atom such as platinum, palladium, or nickel. The present invention also relates to method of forming compounds containing aromatic C—O, C—N, and C—C bonds using the transition metal catalysts.

2. Brief Description of the Related Art

Mild, aromatic or vinylic substitution to form C—O, C—N, and C—C bonds is a difficult transformation. For reactions of unactivated aryl halides, direct, uncatalyzed substitutions and copper-mediated couplings typically require temperatures of 100° C. or greater (Bacon, R. G. R.; Rennison, S. C. J. Chem. Soc. ( C ) 1969, 312-315; Marcoux, J. F.; Doye, S.; Buchwald, S. L. J. Amn. Chem. Soc. 1997, 119, 10539-10540; Kalinin, A. V.; Bower, J. F.; Riebel, P.; Snieckus, V. J. Org. Chem. 1999, 64, 2986-2987).

Alternative approaches have suffered similar drawbacks and disadvantages. For example, diazotization and displacement with oxygen or nitrogen nucleophiles is generally limited in scope and uses stoichiometric amounts of copper in its mildest form (March, J. In Advanced Organic Chemistry John Wiley and Sons: New York, 1985; pp 601). Recently, palladium catalysts for the formation of diaryl and alkyl aryl ethers from unactivated aryl halides have been shown to be useful in these reactions (Mann, G.; Incarvito, C.; Rheingold, A. L.; Hartwig, J. F. J. Am. Chem. Soc. 1999, 121, 3224-3225). However, this system for C—O bond-formation as well as similar systems (Aranyos, A.; Old, D. W.; Kiyomori, A.; Wolfe, J. P.; Sadighi, J. P.; Buchwald, S. L. J. Am. Chem. Soc. 1999, 121, 4369-4378) required temperatures similar to those for copper-mediated processes (Bacon, R. G. R.; Rennison, S. C. J. Chem. Soc. ( C ) 1969, 312-315; Marcoux, J. F.; Doye,. S.; Buchwald, S. L. J. Am. Chem. Soc. 1997, 119, 10539-10540; Kalinin, A. V.; Bower, J. F.; Riebel, P.; Snieckus, V. J. Org. Chem. 1999, 64, 2986-2987; Boger, D. L.; Yohannes, D. J. Org. Chem. 1991, 56, 1763; Fagan, P. J.; Hauptman, E.; Shapiro, R.; Casalnuovo, A. J. Am. Chem. Soc. 2000, 122, 5043-5051). In addition, several catalysts have been shown to induce aromatic C—N bond-formation from aryl halides and sulfonates. Yet, the termperatures, for general reactions remain high in many cases, and the selectivities for formation of the desired aniline derivative instead of the undesired arene or diarylamine are often lower than optimal for synthetic applications.(Wolfe, J. P.; Buchwald, S. L. J. Org. Chem. 2000, 65, 1444; Wolfe, J. P.; Buchwald, S. L. J. Org. Chem. 2000, 65, 1158; Huang, J.; Grassa, G.; Nolan, S. P. Org. Lett. 1999, 1, 1307; Hartwig, J. F.; Kawatsura, M.; Hauck, S. I.; Shaughnessy, K. H.; Alcazar-Roman, L. M. J. Org. Chem. 1999, 64, 5575; Stauffer, S. I.; Hauck, S. I.; Lee, S.; Stambuli, J.; Hartwig, J. F. Org. Lett. 2000, 2, 1423) Finally, catalysts have been developed for aromatic or vinylic C—C bond formation, but again the conditions for these reactions are often harsh.(Suzuki, A. J. Organomet. Chem. 1999, 576, 147; Buchwals, S. L.; Fox, J. M. The Strem Chemiker, 2000, 18, 1; Zhang, C; Huang, J.; Trudell, M. L.; Nolan, S. P. J. Org. Chem. 1999, 64, 3804; Beletskaya, I. P. Cheprakov, A. V. Chem. Rev. 2000, 100, 3009; Littke, A. F.; Fu, G. C. J. Org. Chem. 1999, 64, 10; Shaughnessy, K. H.; Hartwig, J. F. J. Am. Chem. Soc. 1999, 121, 2123) In particular for each of these three classes of reactions, the bond-forming processes are especially difficult to conduct under mild conditions with high selectivity when using chloroarenes.

Unfortunately, reaction conditions such as those described above are quite harsh and require special equipment and techniques to accomplish even small scale syntheses. In addition, larger scale reactions of these reactions, such as those used in large-scale pharmaceutical manufacturing, are generally impractical and expensive due to these extreme reaction conditions. What is needed in the art is a catalytic method of aromatic or vinylic carbon-oxygen, carbon-nitrogen, and carbon-carbon bond formation that occurs under mild conditions (e.g., room temperature and atmospheric pressure) and that is easily scalable for large-scale synthesis, for example, in the pharmaceutical industry. The present invention is believed to be an answer to that need.

DETAILED DESCRIPTION OF THE INVENTION

It now has been surprisingly found, in accordance with the present invention, that a solution is provided to the problem of providing a general and efficient catalytic method of aromatic or vinylic carbon-oxygen, carbon-nitrogen, and carbon-carbon bond formation between two substrates that occurs under mild conditions (e.g., room temperature and atmospheric pressure). The present inventors have solved this problem by utilizing a catalyst that includes a transition metal catalyst comprising a Group 8 metal and a substituted ferrocenylphosphineligand. The catalyst is useful in a general and efficient process of formation of reaction products containing an aromatic carbon-oxygen, carbon-carbon, or carbon-nitrogen bond. Production of carbon-oxygen, carbon-carbon, or carbon-nitrogen bonds between substrates under mild conditions is particularly advantageous in the pharmaceutical industry where active starting substrates can be rapidly degraded by harsh chemical coupling conditions. The aromatic carbon-oxygen, carbon-carbon, or carbon-nitrogen bonds are formed under mild conditions and in the presence of the catalyst using a variety of starting substrates, most notably aryl halide reagents, aryl sulfonate reagents, alkoxide reagents, siloxide reagents, alcohol reagents, silanol reagents, amine reagents, organoboron reagents, organomagnesium reagents, organozinc reagents, malonate reagents, cyanoacetate reagents, and olefinic reagents. In addition to forming an aromatic carbon-oxygen bond between two distinct substrates, the catalyst and method of the present invention is also useful in intramolecular reactions, such as intramolecular etherification, amination, or vinylation where a single compound comprises each of the two substrates.

As defined herein, the term “substrate” includes distinct compounds possessing the above reactive groups (for example, aryl halides, aryl sulfonates, alkoxides, alcohols, siloxides, silanols, amines or related compounds with an N—H bond, organoborons, organomagnesiums, organozincs, malonates, cyanoesters, and olefinic compounds) as well as a single compound that includes reactive groups such as aryl halides, aryl sulfonates, alkoxides, alcohols, siloxides, silandls, amines or related compounds with an N—H bond, organoboron, organomagnesium, organozinc, malonate, cyanoester, and olefinic groups, such that an intramolecular reaction can take place in the presence of the catalyst of the present invention. As defined herein, the term “aromatic” refers to a compound whose molecules have the ring structure characteristic of benzene, naphthalene, phenanthroline, anthracene, related heterocycles such as pyridines, pyrimidines, thiophenes, furans, pyrroles, and the like. The phrase “aromatic carbon-oxygen, carbon-nitrogen, or carbon-carbon bond” refers to a covalent bond between a carbon atom of an aromatic or heteroaromatic ring of a first substrate, and an oxygen, nitrogen, or carbon atom of a second substrate. The terms “amine” and “amine reagent” are broadly defined herein to encompass primary amines, secondary amines, alkyl amines, benzylic amines, aryl amines, as well as related compounds with N—H bonds, including carbamates and cyclic or heterocyclic amine compounds.

As indicated above, the transition metal catalyst of the present invention includes a transition metal atom complexed with a ferrocenyl ligand. In one embodiment, the ferrocenyl ligand portion of the catalyst is represented by the formula:

wherein R, R′, and R″ are organic groups having 1-15 carbon atoms, n=1-5, and m=0-4. Within the ferrocenyl ligand, R can be any organic group possessing 1-15 carbon atoms, preferably 2-8 carbon atoms, and more preferably 2-5 carbon atoms. In one preferred embodiment, R possesses 4 carbon atoms, and is a tertiary butyl group (tBu). R′ can also be any organic group possessing 1-15 carbon atoms, with or without additional substitutents such as halides, and the like. More preferably, R′ possesses 1-10 carbon atoms, and most preferably 2-8 carbon atoms. In one embodiment, R′ may be phenyl, MeO—C 6 H 4 , F 3 C—C 6 H 4 , methyl, or o-tolyl. In addition, the number of R′ groups preferably ranges from 1-5, most preferably either 4 or 5. R″ can also be any organic group possessing 1-15 carbon atoms. Preferable substituents for R″ include methyl, ethyl, propyl, aminoalkyl, 1-dialkylaminoethyl, 1-alkoxyethyl, phenyl, methoxyphenyl, halophenyl, naphthyl, and the like. The number of R″ groups ranges from 0-4.

In one preferred embodiment, the transition metal catalyst is a palladium complex with a ferrocenyl ligand having the formula:

wherein R′ is phenyl, MeO—C 6 H 4 , F 3 C—C 6 H 4 , methyl, or o-tolyl, R is tert-butyl, and n is 4 or 5.

In one particularly preferred embodiment, the transition metal catalyst is a palladium complex with a ferrocenyl ligand having the formula:

The transition metal atom or ion is required to be a Group 8 transition metal, that is, a metal selected from iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium, and platinum. More preferably, the Group 8 metal is palladium, platinum, or nickel, and most preferably, palladium. The Group 8 metal may exist in any oxidation state ranging from the zero-valent state to any higher variance available to the metal. The catalyst may be formed from a mixture of P(C 5 H 4 FeC 5 H 5 )(t-Bu) 2 , Pd(OAc) 2 , NaO-t-Bu and PhCl according to Equation 1.

In the presence of a Group 8 metal, such as iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium, or platinum, the ferrocenyl ligand is formed into an active catalyst that is useful in catalyzing reactions that form carbon-oxygen, carbon-nitrogen, or carbon-carbon bonds between the substrates.

The transition metal catalyst may be synthesized first and thereafter employed in the reaction process. Alternatively, the catalyst can be prepared in situ in the reaction mixture. If the latter mixture is employed, then a Group 8 catalyst precursor compound and the ferrocenyl ligand are independently added to the reaction mixture wherein formation of the transition metal catalyst occurs in situ. Suitable precursor compounds include alkene and diene complexes of the Group 8 metals, preferably, di(benzylidene)acetone (dba) complexes of the Group 8 metals, as well as, monodentate phosphine complexes of the Group 8 metals, and Group 8 carboxylates or halides. In the presence of the ferrocenyl ligand, in situ formation of the transition metal catalyst occurs. Non-limiting examples of suitable precursor compounds include [bis-di(benzylidene)acetone]palladium (0) as shown in Eq. 1, tetrakis-(triphenylphosphine)-palladium (0), tris-[di(benzylidene)acetone]palladium (0), tris-[di(benzylidene)acetone]-dipalladium (0), palladium acetate, palladium chloride, and the analogous complexes of iron, cobalt, nickel, ruthenium, rhodium, osmium, iridium, and platinum.

Group 8 metals supported on carbon, preferably, palladium on carbon, can also be suitably employed as a precursor compound. Preferably, the catalyst precursor compound is bis-[di(benzylidene)acetone]palladium(0).

As indicated above, the present invention is also directed to a method of forming a compound having an aromatic carbon-oxygen, carbon-carbon, or carbon-nitrogen bond, comprising the step of reacting a first substrate and a second substrate in the presence of the transition metal catalyst described above. Each of these steps and components are described in more detail below.

The method of the present invention optionally takes place in the presence of a base. Any base may be used so long as the process of the invention proceeds to the product. Non-limiting examples of suitable bases include alkali metal hydroxides, such as sodium and potassium hydroxides; alkali metal alkoxides, such as sodium t-butoxide; metal carbonates, such as potassium carbonate, cesium carbonate, and magnesium carbonate; phosphates such as trisodium or tripotassium phosphate; alkali metal aryl oxides, such as potassium phenoxide; alkali metal amides, such as lithium amide; tertiary amines, such as triethylamine and tributylamine; (hydrocarbyl)ammonium hydroxides, such as benzyltrimethylammonium hydroxide and tetraethylammonium hydroxide; and diaza organic bases, such as 1,8-diazabicyclo[5.4.0]-undec-7-ene and 1,8-diazabicyclo-[2.2.2.]-octane, and organic or alkali metal fluorides such as tetrabutylamonium fluoride or potassium fluoride. Preferably, the base is an alkali hydroxide, alkali alkoxide, alkali carbonate, alkali phosphate or alkali fluoride, more preferably, an alkali alkoxide, and most preferably, an alkali metal C 1-10 alkoxide.

The quantity of base which may be used can be any quantity which allows for the formation of the product. Preferably, the molar ratio of base to arylating compound ranges from about 1:1 to about 5:1, and more preferably between about 1:1 and 3:1.

As an alternative embodiment of this invention, the catalyst may be anchored or supported on a catalyst support, including a refractory oxide, such as silica, alumina, titania, or magnesia; or an aluminosilicate clay, or molecular sieve or zeolite; or an organic polymeric resin.

The quantity of transition metal catalyst which is employed in the method of this invention is any quantity which promotes the formation of the desired product. Generally, the quantity is a catalytic amount, which means that the catalyst is used in an amount which is less than stoichiometric relative to either of the substrates. Typically, the transition metal catalyst ranges from about 0.01 to about 20 mole percent, based on the number of moles of either the first substrate or the second substrate used in the reaction. Preferably, the quantity of transition metal catalyst ranges from about 0.01 to about 2 mole percent, and more preferably from about 0.1 to about 2 mole percent, based on the moles of either substrate. In addition, the ratio of ferrocenyl ligand to Group 8 metal is preferably in the range from about 3:1 to about 0.25:1, more preferably from about 0.5:1 to about 2:1, and most preferably from about 0.8:1 to about 3:1.

The method described herein may be conducted in any conventional reactor designed for catalytic processes. Continuous, semi-continuous, and batch reactors can be employed. If the catalyst is substantially dissolved in the reaction mixture as in homogeneous processes, then batch reactors, including stirred tank and pressurized autoclaves, can be employed. If the catalyst is anchored to a support and is substantially in a heterogeneous phase, then fixed-bed and fluidized bed reactors can be used. In the typical practice of this invention, the substrates, the catalyst, and any optional base are mixed in batch, optionally with a solvent, and the resulting mixture is maintained at a temperature and pressure effective to prepare the aromatic product containing a C—O, C—C, or C—N covalent bond.

Any solvent can be used in the process of the invention provided that it does not interfere with the formation of the product. Both aprotic and protic solvents and combinations thereof are acceptable. Suitable aprotic solvents include, but are not limited to, aromatic hydrocarbons, such as toluene and xylene, chlorinated aromatic hydrocarbons, such as dichlorobenzene, and ethers, such as dimethoxyethane, tetrahydrofuran or dioxane. Suitable protic solvents include, but are not limited to, water and aliphatic alcohols, such as ethanol, isopropanol, and cyclohexonol, as well as glycols and other polyols. The amount of solvent which is employed may be any amount, preferably an amount sufficient to solubilize, at least in part, the reactants and base. A suitable quantity of solvent typically ranges from about 1 to about 100 grams solvent per gram reactants. Other quantities of solvent may also be suitable, as determined by the specific process conditions and by the skilled artisan.

Generally, the reagents may be mixed together or added to a solvent in any order. Air is preferably removed from the reaction vessel during the course of the reaction, however this step is not always necessary. If it is desirable or necessary to remove air, the solvent and reaction mixture can be sparged with a non-reactive gas, such as nitrogen, helium, or argon, or the reaction may be conducted under anaerobic conditions. The process conditions can be any operable conditions which yield the desired product. Beneficially, the reaction conditions for this process are mild. For example, a preferred temperature for the process of the present invention ranges from about ambient, taken as about 22° C., to about 150° C., and preferably, from about 25° C. to about 70° C. The process may be run at subatmospheric pressures if necessary, but typically proceeds sufficiently well at about atmospheric pressure. The process is generally run for a time sufficient to convert as much of the substrates to product as possible. Typical reaction times range from about 30 minutes to about 24 hours, but longer times may be used if necessary.

The product can be recovered by conventional methods known to those skilled in the art, including, for example, distillation, crystallization, sublimation, and gel chromatography. The yield of product will vary depending upon the specific catalyst, reagents, and process conditions used. For the purposes of this invention, “yield” is defined as the mole percentage of product recovered, based on the number of moles of starting reactants employed. Typically, the yield of product is greater than about 25 mole percent. Preferably, the yield of product is greater than about 60 mole percent, and more preferably, greater than about 75 mole percent.

The following examples are intended to illustrate, but in no way limit the scope of the present invention. All parts and percentages are by weight and all temperatures are in degrees Celsius unless explicitly stated otherwise.

B. Amination Reactions of Aryl Halides

General Methods, Procedure A

A typical procedure is given for the reaction of Entry 1 in Table 2. A 4 ml vial was charged with bromobenzene (171 mg, 1.10 mmol), diphenylamine (169 mg, 1.00 mmol), Pd(dba) 2 (5.9 mg, 1 mol %), Ph 5 FcP(t-Bu) 2 (7.1 mg, 2 mol %), and sodium tert-butoxide (144 mg, 1.50 mmol). Anhydrous toluene (1 ml) was added into the mixture, and the vial was then sealed with a cap containing PTFE septum. The reaction mixture was stirred at room temperature for 1 h. After the starting aryl halide was consumed detected, as determined by GC, the reaction solution was directly absorbed onto silica gel, and the product was isolated by eluting with hexane/ethyl acetate to give 244 mg (99%) of triphenylamine as a white solid. Reaction of chlorobenzene (62 mg, 0.55 mmol) with diphenylamine (85 mg, 0.50 mmol) proceeded at 80° C. over 21 h to give triphenylamine (121 mg, 98%).

General Methods

1 H and 13 C NMR spectra were recorded on a Bruker DPX 400 MHz Spectrometer, General Electric QE 300 MHz spectrometer, or a General Electric Omega 500 spectrometer with tetramethylsilane or residual protiated solvent used as a reference. Elemental analyses were performed by Robertson Microlabs, Inc., Madison, N.J. Yields for final product in Table 26 refer to isolated yields of compounds of greater than 95% purity, as determined by 1 H-NMR and capillary gas chromatography (GC). All 31 P and 13 C NMR spectra were proton decoupled. GC analyses were performed on a HP-5890 series II instrument equipped with an HP3395 intelligent recorder. GC/MS spectra were recorded on a HP5890 instrument equipped with a HP5971A Mass Spectral Analyzer. Both GC and GC/MS were performed using a HP-1 methyl silicone column. Yields reported in Table 26 are an average of two runs. Methyl acrylate, 2-bromoanisole, 4-bromoanisole, 4-bromotoluene, 1-bromonapthalene, 4-bromobenzotrifluoride, bromobenzene, and 2-(3-bromophenyl)-1,3-dioxolane were purchased from Aldrich and used without further purification. Dioxane and dimethylformamide were purchased as anhydrous grade and stored in a drybox. Propyl methyl ketone and butyronitrile were purchased from Aldrich and degassed before use. Triethylamine was purchased from Aldrich and dried over molecular sieves before use. Ether, toluene, tetrahydrofuran, benzene, and pentane were distilled from sodium/benzophenone.

General Procedure for Room Temperature Palladium Catalyzed Heck Reactions

The reaction conditions and results are shown in Table 26. A typical procedure is given for the reaction of Entry 1 in Table 26.

A 4 mL vial was charged with 4-bromoanisole (187 mg, 1.00 mmol), Pd(dba) 2 (14.4 mg, 0.0250 mmol), Ph 5 FcP(t-Bu) 2 (35.5 mg, 0.0500 mmol), and 1 mL of anhydrous DMF. The vial was sealed with a cap containing a PTFE septum and removed from the drybox. NEt 3 (167 μL, 1.20 mmol) was added by syringe. The reaction was stirred at room temperature for 20 h. The reaction mixture was then poured into a saturated lithium chloride solution and extracted (3×10 mL) with ether. The ether was evaporated under vacuum, and the product was isolated by flash chromatography, eluting with 15% ethyl acetate/hexanes, to give 176 mg (92%) of 3-(4-methoxy-phenyl)acrylic acid methyl ester.
