Abstract
Process for the preparation of acetidino-thiazolidin-methanocarboxylic acid esters and of the compounds 7-amino-3-deacetyloxymethyl-3-formyl-isocephalosporaic acid obtained therefrom by ring closure, characterized in that a 3-acyl-acetidino compound [ 3,2-d] -thiazolidin-2-on N 1 -unsubstituted, 4,4-disubstituted, is reacted with diformylmethylene-methanecarboxylic acid ester and, if desired, an ester of 3-acyl- α -diformylmethyl 2-Oxo-1-acetidino [3,2-d] thiazolidin-methanocarboxylic acid, 4,4-disubstituted, is treated with an acid medium under dissociation of the 5-membered sulfur-nitrogen ring and formation of a new one of 6 members and/or, if desired, in one compound obtained one substituent is transformed into another and/or if desired, a mixture of isomers obtained is separated into the different isomers.
