Twenty 3-acetoxymethyl cephalosporinderivatives, with various cinnamoyl (3-phenyl-2-propenoyl) substituted groups at the 7beta-position, were synthesized and evaluated for antibacterial activity in vitro. Some of these cephalosporinderivatives showed good selective activity against Gram-positive bacteria. Although substitution on the aromatic ring of cinnamoyl moiety generally reduced antimicrobial
