Abstract

A procedure for the preparation of new substituted β-lactams of formula (I) **(See formula)** where X represents hydrogen or halogen or a substituted anino or amino group; Y represents hydrogen or, in cases where X is hydrogen or halogen, Y can be halogen; R3 represents hydrogen or a group of formula (II) **(See formula)** where R4 represents a carboxylic acid group or a salt, ester, thioester or amide derived from a carboxylic acid group and A represents a group of formula (III) **(See formula)** where R1 represents hydrogen or an alkyl, alkenyl, alkynyl or aryl group and R2 represents an acyl group whose process is characterized by reacting a compound of formula (VI) **(See formula)** where X, Y and R3 are as defined above and Z is hydrogen or an alkyl, alkenyl, alkynyl or aryl group, with a lead tetracarboxylate of formula (VIA) Pb (OR2) 4 (VIA) where R2 is acyl.
