Title: Manufacture of new acylmercapto compounds
Filed: 1953-11-13
Abstract: The invention comprises S-aminoacylmercapto compounds of the formula <FORM:0780943/IV (a)/1> wherein A is an unsubstituted or substituted amino group, X and Y are divalent organic radicals and Z is a monovalent electron-attracting substituent, such as hydroxyl or carboxyl groups, both of which may be functionally converted, or a sulphonyl or nitro group or halogen.  The S-aminoacylmercapto compounds are prepared by reacting the compounds of formul  A-X-B1 and B2-Y-Z, wherein B1 is a carboxyl group or a reactive derivative thereof, such as a halide, anhydride or azide, and B2 is a mercapto group or a salt thereof, A, X, Y and Z being as defined above. Specified substituents on A are acyl, acylaminoacyl, aminoacylaminoacyl, alkyl, alkenyl, cycloalkyl, aryl, aralkyl and/or heterocyclic radicals, such as the acetyl, aminoacetyl, aminoacetyl-aminoacetyl, carbobenzyloxyaminoacetyl, carbobenzyloxyaminoacetylaminoacetyl, benzoyl, phthalyl, nitrophenoxyacetyl, carbobenxyloxy and thiocarbobenzyloxy groups. A may also be a dimethyl- or diethyl-amino, piperidino or morpholino group.  Specified X and Y groups are methylene, ethylene, propylene and phenylene.  The S-aminoacylmercapto compounds form salts with acids and, insofar as they contain acid groups, also with bases.  The compounds are used for the introduction of aminoacyl groups into compounds such as alcohols or amines.  Compounds wherein A is an acylamino group may be converted into the corresponding amino compounds by treatment in an acid medium without rupture of the C-S bond.  In examples: (1) a mixed anhydride prepared by reacting benzoylamino-acetic acid and ethyl chloroformate is reacted with mercapto-acetic or -propionic acid to give S-benzoylaminomercapto-acetic or -propionic acid, phthalylaminoacetic acid and carbobenzyloxyaminoacetic acid are reacted similarly, by way of the anhydride, with mercaptoacetic acid to give S - (phthalylamino - acetyl) - mercaptoacetic acid and S-(carbobenzyloxyamino-acetyl)-mercaptoacetic acid; (2) the hydrochloride of aminoacetyl chloride is reacted with mercaptoacetic acid to give S-aminoacetyl-mercaptoacetic acid; (3) as in (1) benzoylamino-acetic acid or carbobenzyloxyaminoacetic acid is converted into the anhydride and reacted with thiosalicylic acid to give S - (benzoylamino-acetyl)-or -(carbobenzyloxyamino-acetyl)-thiosalicylic acid; (4) as in (1) N-[N-(carbobenzyloxyamino - acetyl) - aminoacetyl] - aminoacetic acid converted into the anhydride and reacted with mercaptoacetic acid to give S-[N-(N-carbobenzyloxyamino - acetyl - aminoacetyl) - aminoacetyl] - mercaptoacetic acid; (5) S-carbobenzyloxyaminoacetyl - mercaptoacetic acid is hydrolysed with a solution of hydrogen bromide in glacial acetic acid to give the hydrobromide of S - aminoacetyl - mercaptoacetic acid; (6) the product of (4) is hydrolysed as in (5) to give the hydrobromide of S-[N-(N-aminoacetyl - aminoacetyl) - aminoacetyl] - mercaptoacetic acid.
