The compounds of formula I can be prepared as salts, in particular pharmaceutically acceptable salts. If the compounds of formula I have, for example, at least one basic center, they can form acid addition salts. These are formed, for example, with strong inorganic acids, such as mineral acids, for example sulfuric acid, phosphoric acid or a hydrohalic acid, with strong organic carboxylic acids, such as alkanecarboxylic acids of 1 to 4 carbon atoms which are unsubstituted or substituted, for example, by halogen, for example acetic acid, with saturated or unsaturated dicarboxylic acids, for example oxalic, malonic, succinic, maleic, fumaric, phthalic or terephthalic acid, with hydroxycarboxylic acids, for example ascorbic, glycolic, lactic, malic, tartaric or citric acid, with amino acids, (for example aspartic or glutamic acid or lysine or arginine), or benzoic acid, or with organic sulfonic acids, such as (C 1 -C 4 )-alkyl- or aryl-sulfonic acids which are unsubstituted or substituted, for example by halogen, for example methane- or p-toluene sulfonic acid. Corresponding acid addition salts can also be formed if the compounds of formula I have an additional basic center. The compounds of formula I having at least one acid group (for example COOH) can also form salts with bases. Suitable salts with bases are, for example, metal salts, such as alkali metal or alkaline earth metal salts, for example sodium, potassium or magnesium salts, or salts with ammonia or an organic amine, such as morpholine, thiomorpholine, piperidine, pyrrolidine, a mono-, di- or tri-lower alkylamine, for example ethyl-, tert-butyl-, diethyl-, diisopropyl-, triethyl-, tributyl- or dimethylpropylamine, or a mono-, di- or trihydroxy lower alkylamine, for example mono-, di- or triethanolamine. Corresponding internal salts may furthermore be formed. Salts which are unsuitable for pharmaceutical uses but which can be employed, for example, for the isolation or purification of free compounds I or their pharmaceutically acceptable salts, are also included.

Preferred salts of the compounds of formula I include monohydrochloride, hydrogensulfate, methanesulfonate, phosphate or nitrate.

All stereoisomers of the compounds of the instant invention are contemplated, either in admixture or in pure or substantially pure form. The compounds of the present invention can have asymmetric centers at any of the carbon atoms including any one of the R substituents. Consequently, compounds of formula I can exist in enantiomeric or diastereomeric forms or in mixtures thereof. The processes for preparation can utilize racemates, enantiomers or diastereomers as starting materials. When enantiomeric or diastereomeric products are prepared, they can be separated by conventional methods for example, chromatographic or fractional crystallization.

It should be understood that the present invention includes prodrug forms of the compounds of formula I such as alkylesters of acids or any known prodrugs for lactam derivatives.

The compounds of the instant invention may, for example, be in the free or hydrate form, and may be obtained by methods exemplified by the following descriptions.

The compounds of formula I may be prepared by the exemplary processes described in the following reaction schemes. Exemplary reagents and procedures for these reactions appear hereinafter and in the working Examples.

In one method, lactam, II, is converted to IV by protection followed by substitution (via IIa) or by substitution followed by protection (via III). The CBZ protecting group or trifluoroacetyl group may be used in place of the BOC-group, for example.

Compound IV is then converted to compound V by alkylation with haloamide VI. Haloamide VI is obtained from bromoacetyl chloride (or other halo acid chloride) by acylation under standard conditions. The protecting group is then removed from V by treatment with TFA to provide VII.

Compounds of type VII can then be converted to the target compounds as shown in the schemes below. In one method, an isothiocyanate VIII is converted to compound IX using sodium cyanamide. The salt IX is then coupled to compound VII by using 1-[3-(dimethylamino)propyl]-3-ethyl-carbodiimide (WSC or EDCI) in DMF to yield the targets.

In another method, amine XI is converted to intermediate XII by reaction with XIII or XIV. Intermediate XII is then converted to target compounds IA by reaction in ethanol, ethyl acetate, DMF and the like. In the case where XII contains the MeS group, a mercury salt (such as mercuric acetate) can be used to speed the reaction.

In another route, compound VII can be reacted with XIII or XIV to prepare XV. Compound XV is then converted to IA by reaction with an amine in a solvent like acetonitrile or ethanol or DMF.

Other compounds of type IA can be obtained by acylation with an acid chloride or acid anhydride in the presence of sodium hydride.

(where R 11 is alkyl, arylalkyl, aryl or heteroaryl).

The target compounds can also be prepared by converting compounds of type IV to esters of type XVI as described above. These esters can be elaborated in similar manner to provide XVII. Conversion of the ester XVII to the acid XVIII can be accomplished, for example, by hydrogenation if R 11 is benzyl or by hydrolysis if R 11 is methyl, ethyl, or benzyl.

Compounds of the invention of type IB can be prepared by hydrolysis of compounds IA using aqueous HCl, or sodium hydroxide or other acids or bases or other methods for the conversion of nitrites to amides known in the literature.

Compounds of the invention of type IC or ID can be prepared from thioureas of type XXI. The reaction is carried out in the presence of a coupling agent such as ethyl 3-(dimethylamino)propylcarbodiimide hydrochloride (WSC, EDCI) or the like. Alternatively, the reaction can be carried out in the presence of a mercury salt (such as mercuric chloride, mercuric acetate, mercuric trifluoroacetate, mercuric oxide and the like) or salts of other metals such as silver, cadmium and the like.

Alternatively, compounds such as IC or ID can be obtained from thioureas of type XXII in a similar manner.

Thioureas of type XXI and type XXII can be prepared by methods known in the literature. For example, an isothiocyanate can be reacted with a nitrogen-containing compound in an inert solvent (DMF, acetonitrile, THF, or the like) optionally in the presence of a base such as triethylamine, sodium hydride, tert-butylimino-tris(pyrrolidino)phosphorane, Hunig's base, and the like.

Alternatively, a multi-step procedure may be used to prepare compounds of type IE (where Y=Ra—C(O)).

In addition, reagents such as XXIII may be used as described above for the synthesis of compounds of type IC and ID
