Abstract
The 2β-(O-dibenzyl-phosphate)-oxymethyl-2α-methyl penam 3α-carboxylic acid benzyl ester and 3β-(O-dibenzyl-phosphate)-3α-methyl cepham 4α-carboxylic acid benzyl ester were synthesized. The conversion of the acyclic azetidione disulfides 1a–c prepared by Kamiya’s procedure to their bicyclic penam 2a–c and cefam 3a–c derivatives are described.
