  N-Aryl Modification in γ-Lactam: Design and Synthesis of Novel Monocyclic γ-Lactam Derivatives as Inhibitor for Bacterial Propagation

  摘要：

  In search of novel gamma-lactam antibacterial agents as non-beta-lactam mimics of some c-lactam antibiotics, N-aryl modification in the gamma-lactam ring has been made to synthesize compounds 4-8 in two to six steps. Compound 4 was synthesized using the intermolecular Michael addition of diethyl N-(6-coumarinyl)-2-aminomalonate and 3-aryl/(2-heteroaryl) acryloyl chloride followed by intramolecular amidification. Hydrolysis and stereoselective decarboxylation of 4 resulted in the formation of trans-gamma-lactam carboxylic acids (5), which on side chain homologation followed by saponification of the intermediate gamma-lactam monoester (7) afforded gamma-lactam carboxylic derivatives 8. Moderate to good bacterial growth inhibition was observed for some of the synthesized compounds against E. coli and S. aureus.
