Synthesis and antibacterial activity of 2-[(methoxycarbonyl)methylene]cephalosporins

The synthesis and in vitro activities of a series of 2-[(methoxycarbonyl)methylene]-3-cephem-4-carboxylic acids with methyl or acetoxymethyl at the 3-position are described. The key step in the synthesis includes the stereospecific formation of the 2-[(Z)
