Abstract
Improvements introduced in the main patent object No. 382,211 by: A method for the preparation of heterocyclic compounds of formula (IIC): **(See formula)** where R is an esterified carboxylic acid group; R8 represents an aralkyl group; R1 represents a group of formula (III) or (IIIA) **(See formula)** where R7 is hydrogen or an alkyl, aralkyl or aryl group with any one of these groups being able to be substituted; the improvements of which are to react a penicillanic acid derivative of formula (IA) **(See formula)** where R8 and R are those defined when describing the formula (IIC) in a substantially anhydrous liquid medium, with a strong base that does not separate the β-lactam ring from the penicillanic acid derivative (IA) and a formula motif (IIIB) : Z - CH2 - C = C - R7 (IIIB) where R7 is the one defined when describing formulas (III) and (IIIA) and Z is an atom or reactive group capable of effecting the introduction of the group- [CH2 - C = C - R7] on the sulfur atom.
