Abstract

A series of 2α-alkoxymethyl cephem sulfones were prepared by nucleophilic addition of a variety of alcohols to exo-2-methylene cephem sulfones. The 2α-alkoxymethyl group was introduced with the aim of improving the inhibitory activity against human leukocyte elastase (HLE) over the unsubstituted compounds. However, against HLE the in vitro activity was still inferior to that shown by the C-2 unsubstituted cephem sulfones.
