Asymmetric synthesis of new β-lactam lipopeptides as bacterial signal peptidase i inhibitors

The transmembrane bacterial enzyme, signal peptidase I, is recognized as being a promising target for reducing the emergence of drug resistance. The asymmetric synthesis and the biological evaluation of original β-lactam lipopeptides have been performed t

Syntheses of (6S)-cephalosporins from 6-aminopenicillanic acid

Two practical routes to (6S,7S)-cephalosporins from 6-aminopenicillanic acid (6-APA) are described. In the first, 6-APA was converted to (2S,4S,5S,6S)-penicillin sulfoxide 49, which underwent Morin ring expansion to a protected (6S,7S)-cephem 50. In the s
