Abstract

Process for the preparation of a hydroxylated secondary or tertiary amine compound having a hydroxyl function .beta. to the amine function, according to which a primary or secondary amine compound is reacted with a compound containing an epoxy function in the presence of a phase transfer catalyst.

Description

BACKGROUND OF THE INVENTION

(i) Field of the Invention

The present invention relates to a new process for the preparation of a hydroxylated secondary or tertiary amine compound starting, respectively, from a primary or secondary amine compound, which does not require the employment of an organic solvent such as alcohols or ketones.

(ii) Description of the Related Art

It is known to prepare hydroxylated secondary or tertiary amine compounds, containing a hydroxyl group .beta. to the amine group, by having a primary or secondary amine compound, respectively, react with an epoxy compound, in an organic solvent medium, generally comprising an alcohol or a ketone.

The compounds thus formed give rise to the disadvantage in that they contain traces of organic solvent from the process, making them ill-suited for use in cosmetics, pharmaceuticals, or in any products where the absence of an organic solvent is a requirement.

French Patent 2,099,030 describes a process for the preparation of a compound N-(hydroxyhydrocarbyl)-N-(alkylaminocarboxylate) by reaction between a 1,2-epoxide of hydrocarbide compound and an N-substituted aminocarboxylic acid, in an aqueous medium, optionally in the presence of an alcohol.

However, in order to obtain acceptable yields, this reaction must be carried out in a reactor under very strong agitation, in a manner which is incompatible with implementation on an industrial scale.

In addition, French Patent 2,099,030 recommends purifying the resulting product of the reaction by treating it with an organic solvent medium brought to reflux. It is understood that such purification method leads to the obtaining of a product which cannot be made free of organic solvent and, besides, the employment of a solvent brought to reflux conditions gives rise to significant risks relating to the safety of persons.

Besides, H. Rutzen in Fette, Seifen, Anstrichmittel, Vol. 84, No. 3, 1982, Hamburg, pages 87-92, "Quaterernierung von terti aren Aminsalzen mit langkettigen Epoxiden" describes a process for the preparation of quaternary ammonium compounds by reaction of a tertiary amine compound with a compound containing an epoxy function, in the presence of a phase transfer catalyst.

SUMMARY AND OBJECTS OF THE INVENTION

The present invention has as its principal object a process for the preparation of a hydroxylated secondary or tertiary amine compound, which can be employed in the absence of an organic solvent and, which can be carried out with agitation speeds which are compatible with existing industrial reactors.

The present invention thus relates to a process for the preparation of a hydroxylated secondary or tertiary amine compound having a hydroxyl function group .beta. to the amine group starting from, respectively, a primary or secondary amine compound, comprising reacting the primary or secondary amine compound with an epoxy compound in the presence of (i) a phase transfer catalyst and (ii) a mineral base then, if necessary, the hydroxylated secondary or tertiary amine compound which is formed from the phase transfer catalyst is separated.

In a second aspect, the present invention relates to a composition comprising:

(i) at least one hydroxylated secondary or tertiary amine compound having a hydroxyl .beta. to the amine; and (ii) a phase transfer catalyst, the composition being substantially free of organic solvents.

With the foregoing and other objects, advantages and features of the invention that will become hereinafter apparent, the nature of the invention may be more clearly understood by reference to the following detailed description of the invention and to the appended claims.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS,

It has in effect been observed that the presence of a phase transfer catalyst in the reaction medium permitted the resolution of the problems expounded upon above. However, it is essential to carry out the reaction in the presence of a mineral base, at least when the primary or secondary amine is in a free form, such in order to obtain a suitable yield.

In the context of the present invention, a phase transfer catalyst is a chemical compound permitting the reaction between two chemical entities which are found in different phases such as, for example, two liquid entities of different nature.

Advantageously, the primary or secondary amine compound contains at least one oxygen-containing group which can be formed into a salt such as the groups --COO.sup.-, --SO.sub.3.sup.3, --PO.sub.4 H.sup.-, --SO.sub.4.sup.-2 or --PO.sub.3.sup.2-, the groups essentially being in a free or salt form. It should be understood that by free form, it is meant that the oxygen-containing group capable of forming a salt has a counter-ion H.sup.+, and by salt form is meant that the counter-ion consists of an organic or mineral cation, such as 4 or a cation of an NH.sub.4.sup.+ alkaline or alkaline earth metal, such as sodium, potassium or calcium.

More particularly, the primary or secondary amine compound can consist of a carboxyamino compound containing one or two carboxylic groups in free or salt form.

Such carboxyamino compounds can notably consist of amino acids, oligopeptides, peptides, N-acylated amino acids, N-acyl oligopeptides, mono or polycyclic heterocyclic carboxyamino compounds containing from 3 to 14 carbon atoms and at least one nitrogen atom as the heteroatom, or mixtures of these carboxyamino compounds.

The amino acids can consist of .alpha.-amino acids such as sarcosine, asparagine, valine, leucine, isoleucine, threonine, methionine, phenylalanine, tryptophane, lysine, hydroxylysine, alanine, arginine, aspartic acid, cystine, cysteine, glutamic acid, glycine, histidine, proline, hydroxyproline, serine, tyrosine, glutamine, or mixtures of these amino acids.

The N-acylated amino acids and the N-acyl oligopeptides mentioned above are well known. They can notably be prepared according to the processes described in French Patent 2,619,711 or in patent application JP-03/294298.

The heterocyclic carboxyamino compounds which can be employed in the process of the invention can contain, besides a nitrogen heteroatom, from 1 to 3 other heteroatoms chosen among N, O and S. Compounds of such type can consist of carboxylic derivatives of morpholine, pyridine, pyrazine, pyrimidine, purine, quinoleine, and isolquinoleine, of imidazole, pyrazole, thiazole, or oxazole or a compound such as nicotinic acid. A primary or secondary amine compound including a group --SO.sub.3.sup.- can consist of taurine or methyltaurine.

As the primary or secondary amine which can be used as the starting product in the process according to the present invention, there can be mentioned compounds such as chitine or those of the formula (I):

R--NH--G (I) in which R is hydrogen or a C.sub.1 -C.sub.30 radical and G is the residue of a monosaccharide, a disaccharide, a polysaccharide or hexitol.

Preferably R is hydrogen or a C.sub.1 -C.sub.4 alkyl radical.

G can be a monosaccharide such as galactose, fructose, glucose, mannose, xylose, arabinose, lyxose, ribose or ribulose, of a disaccharide such as saccharose, maltose, or lactose, a polysaccharide such as cellulose or starch or hexitol, such as sorbitol, mannitol or galactitol.

The preferred compounds of formula (I) consist of glucamine, N-methylglucamine and glycosamine.

It should be understood that one of the primary or secondary amine compounds described above, or mixtures of these, can be employed.

An epoxy compound which can be employed in the process according to the invention can consist of a compound of formula (II): ##STR1## in which the substituents R.sub.1, R.sub.2, R.sub.3, and R.sub.4, which may be identical or different, are:

X is hydrogen or sulfur, s is equal to 0 or ranges between 1 and 4 and t is equal to 0 or ranges between 1 and 20, with the proviso that at least one of R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is different from hydrogen.

Advantageously three of the substituents R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent hydrogen, the fourth of these substituents being different from hydrogen; more particularly the last substituent can be a C.sub.1 -C.sub.20 alkyl radical, preferably C.sub.8 -C.sub.14.

The phase transfer catalysts employed can be those described in W. P. Weber, G. W. Gorel "Phase Transfer Catalysis in Organic Synthesis"--Springer-Verlag, Berlin, Heidelberg, New-York (1977); C. M. Starks, C. Liotta "Phase Transfer Catalysis. Principles and Techniques"-Academic Press, New York, San Francisco, London (1978); or E. V. Dehmlow, E. S.

This reaction is generally carried out at atmospheric pressure or a temperature which is close to atmospheric pressure. The agitation speed of the reaction medium which is generally employed is less than 1000 rpm, preferably ranging between 500 and 50 rpm.

At the end of the reaction between the primary or secondary amine epoxy compound and the compound, there is obtained a hydroxylated secondary or tertiary amine compound having a hydroxyl group which is .beta. to the amine group in admixture with the phase transfer catalyst. If it is desired to obtain solely the hydroxylated compound, the phase transfer catalyst can be eliminated according to classical methods, well known to persons skilled in the art.

The hydroxylated secondary or tertiary amine compound obtained can be a compound of the formula (III): ##STR2## a compound of formula (IV): ##STR3## or a mixture of the compounds of formulas (III) and (IV).
