Abstract

This invention provides the compounds of the formula (III): <IMAGE> wherein R1 is an alkyl group of up to carbon atoms and R2 is an alkyl group of up to 3 carbon atoms optionally joined to R1 so that R1 and R2 and the carbon atom to which they are attached form a spiro-cyclopentyl or spiro-cyclohexyl ring, and wherein the configuration about the ???-lactam ring is trans, which are useful in the preparation of antibacterial beta -lactam compounds. The invention also discloses a process for the preparation of the compounds of the formula (III).
