## Abstract ‘7‐aminocephalocillanic acid’ **1**, an intermediate for the preparation of new β‐lactam antibiotics was prepared by transforming the β‐lactam carbinol **2a** to the phosphorane **9a** through several steps. Oxydation of **9a** with DMSO/Ac~2~O led directly to the cyclized ester **11a**
