A series of macrocyclic bis-β-lactams has been synthesized in three good yielding steps using a Staudinger [2+2] cycloaddition reaction of ketene derived from phenoxyacetyl chloride as the key step. The reaction provided a diastereomeric mixture of cis-anti-cis (C2-symmetry) and cis-syn-cis

Cycloaddition of azidoacetyl chloride to benzyl D-5,5-dimethyl-5-phenyl-2-thiazoline-4-carboxylate (1a) gave 5-phenyl-6alpha-azidopenicillanate (2a). By catalytic reduction of 2a and reaction with phenoxyacetyl chloride, 5-phenyl-6-epiphenoxymethylpenicillin benzyl ester (4a) was obtained. Oxidation of 4a gave the sulfoxide 6, which was isomerized in the presence
