A combination of a stereoselective addition of benzenethiol to α,β-unsaturated carboxylic acid derivatives and a subsequent substitution reaction of the corresponding sulfonium group with O-alkyl-hydroxamate anion has provided a new practical and stereoselective method for the construction of 3,4-disubstituted cis- and trans-β-lactams. A successful application was demonstrated by the formal asymmetric synthesis of (+)-PS-5.

A combination of stereoselective addition of thiophenol to olefins and subsequent substitution of the corresponding sulfonium group with an O-alkylhydroxamate anion has provided a new practical and stereoselective method for the construction of β-lactams which has been successfully applied to the formal asymmetric synthesis of the carbapenem antibiotic (+)-PS-5 1.
