摘要：
Intermediates (I) for preparing a potent antibacterial, 1-oxadethiacephalosporin, are shown by the following formula ##STR1## (wherein R is a group of acyl-minus-carbonyl derived from a carboxylic or carbonic acid;COB is carboxy or protected carboxy;X is hydrogen or a nucleophilic group;Y is a nucleophilic group; andZ is a leaving group)and prepared from the corresponding exomethylene compound (II) by addition of a compound of formula: Y-Z (in which Y and Z are as defined above).
