ABSTRACT:
.beta.-Lactam compounds which are useful as intermediates for the production of carbapenem or penem derivatives and a process for producing the same. The process comprises reacting a Schiff base with diketene in the presence of an imidazole, reducing the acetyl group of the resulting N-protected-3-acetyl-2-azetidinone-4-carboxylic acid ester, and removing the protecting group for a carboxyl group from the resulting 3-(1-hydroxyethyl)-2-azetidinone-4-carboxylic acid derivative.
