  Synthesis and antibacterial activity of 4- and 8-methoxy trinems

  摘要：

  The synthesis of all the isomers of 8-methoxy-(9S,10S,12R)-10-(1-hydroxyethyl)-11-oxo-1-azatricyclo-[7.2.0.0(3,8])-undec-2-ene-carboxylates 2 and 4-methoxy-(9R,10S,12R)-10-(1-hydroxyethyl)-11-oxo-1-azatricyclo-[7.2.0.0(3.8)]-undec-2-ene-carboxylates 3 is described. The biological data obtained indicated that the (4S,8S)-4-methoxy derivative (3b) is the best compound in terms of microbiological activity, breadth of spectrum of action and stability to hydrolytic enzymes, namely beta-lactamases.
