摘要：
3-Substituted vinyl cephalosporin derivatives represented by the following formula:
wherein R 1 represents a hydroxyl or lower alkoxyl group, X represents a nitrogen atom or a group represented by the formula -CH =, R 2 represents a carboxyl group or a carboxyl group protected with a protecting group, and R 3 is as defined herein, and pharmaoeutically acceptable salts thereof are potent antibacterial agents. Processes for their preparation, intermediates in such processes, and antibacterial compositions containing them as active ingredients are also described.
