Abstract
1346198 Process for penicillamine and its homologues DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT 24 June 1971 [3 July 1970 11 May 1971] 29635/71 Heading C2C The invention comprises a process for making penicillamine or a homologue thereof and also salts thereof, by reacting an aliphatic aldehyde, branched on the α-carbon, with sulphur and ammonia to form a #<SP>3</SP>-thiazoline (I), converting (I) by reaction with hydrogen cyanide into a thiazolidine - 4 - carbonitrile (II), converting (II) by mineral acid hydrolysis at below 80‹ C. into a salt of a 4-carbamoylthiazolidine (the free compounds are also described), and thereafter raising the temperature to above 80‹ C. to form a salt of a 4-carboxy-thiazolidine (III) and an ammonium salt (IV); (IV) is removed and (III) or the free acid is hydrolytically degraded to yield the desired product. The following intermediates are also prepared: 2-isopropyl-5,5- dimethylthiazolidine - 4 - carboxylic acid npropyl ester and penicillamine amide hydrochloride; these compounds arise from modifications of the foregoing process.
