摘要

The total synthesis of (i)-l-methylene-2, 2-dimethyl-7-amino-l-carbacephem-4-carboxylic acid (1) is described. The reaction scheme was essentially that described by Christensen et al. for the synthesis of (f)-1-carbacephems. In vitro antibacterial activities of the 7- phenoxyacetyl and 7-~-a-phenylglycyl derivatives of 1 were compared with those of 7- (phenoxyacetamido) desacetoxycephalosporanic acid and cefalexin. Derivatives of 1 ...
