The structures of all the title compounds have been confirmed by virtue of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra. The characteristics of 13C NMR peaks of the compounds were investigated. The plant growth regulating effects of those compounds were also determined.展开更多
Nine new derivatives of 7 β - (5- methyl- 1- aryl- 1H-1, 2, 3- triazoly- 4- carboxamido) cephalosporins were synthesized by acylction of 7 β -amino group of 7-ACA, 7-ADCA and 7-ACT with 5 -methsyl- 1 -aryl- 1 H- 1,2...Nine new derivatives of 7 β - (5- methyl- 1- aryl- 1H-1, 2, 3- triazoly- 4- carboxamido) cephalosporins were synthesized by acylction of 7 β -amino group of 7-ACA, 7-ADCA and 7-ACT with 5 -methsyl- 1 -aryl- 1 H- 1,2,3-triazoly-4-formyl chloride. The structure of the compounds were confirmed by elementray analysis IR, HNMR and FAB-MS. Some of them showed significant antibacterial activity展开更多
