Abstract

A novel method for the preparation of thioesters starting from Iso‐Fujisawa disulfides is reported. The presence of an acylamino group cis to the disulfide function on the β‐lactam nucleus seems to be an essential requirement for this reaction. In the absence of such a cis‐acylamino group, desulfurization, is the preferred course.
