Design, synthesis and antibacterial activity of novel N-formylhydroxylamine derivatives as PDF inhibitors
Yin,Jia,Zhao,Xu,Tang,Wang
experimental part, p. 695 - 703 (2011/07/29)
A new series of N-formylhydroxylamines 11a-i have been synthesized through a multi-step protocol starting from diethyl malonate. These compounds have been structurally characterized by IR, 1H NMR and HRMS. All the synthesized compounds 11a-i have been screened for antibacterial activities. All the compounds are found to exhibit potent in vitro inhibitory activity against Staphylococcus aureus and relatively weak antibacterial activity against Klebsiella pneumoniae.
