title: Synthesis and antimicrobial activity of a dihydroampicillin and a dihydrocephalexin.
abstract: A dihydroampicillin (3) and a dihydrocephalexin (4) have been synthesized by condensing alpha-(cyclohexa-1, 3-dienyl)glycyl chloride with 6-aminopenicillanic acid (1) and 7-deacetoxycephalosporanic acid (2) respectively. The two antibiotics obtained show enhanced antimicrobial activity towards certain bacterial strains compared with ampicillin and cephalexin.
