Substituted Penicillanic Acid 1,1-Dioxides as &β-Lactam Inhibitors: Studies on 6-Benzylidene- and Hydroxybenzylpenam Sulphones

The preparation of the two epimers of (6R)-6-(α-hydroxybenzyl)penicillanic acid and the corresponding sulphones is described.The absolute configuration about the hydroxy substituted carbon atom has been elucidated by an investigation of the dehydration to
