ABSTRACT:
There are prepared 1-amino-2-mercapto-2-methylpropyl phosphonic acid or 1-amino-2-mercapto-2-methylpropyl alkylphosphinic acids of the formula ##STR1## in which Y is hydroxy or an alkyl group by reacting thiazoline-(3) with a phosphonic acid dialkyl ester or an alkylphosphinic acid alkyl ester and then hydrolytically splitting the thiazolidinyl phosphonic acid dialkyl ester or thiazolidinyl alkylphosphinic acid alkyl ester. The thiazolidinyl compounds are new compounds. The 1-amino-2-mercapto-2-methylpropyl phosphonic acid and the 1-amino-2-mercapto-2-methylpropyl alkylphosphinic acids are needed for pharmaceutical purposes.
