Abstract

A process for the separation of certain N-substituents from azetidin-2-ones from a group of formula (I) ** (see formula) ** Where r is an acyl group or carboxylic acid or an amide derivative, ester or thioester of a carboxylic acid group, of an azetidin-2-one containing said group attached to the nitrogen of the nucleus, whereby said group is replaced by an atom of hydrogen, whose procedure consists of treating an azetidin-2-one with said group attached to the nitrogen of the nucleus with a reagent capable of oxidatively adding to the double bond of said group.
