Microwave enhanced reduction of nitro and azido arenes to N-arylformamides employing Zn–HCOONH4: synthesis of 4(3H)-quinazolinones and pyrrolo[2,1-c][1,4]benzodiazepines
摘要:
Microwave mediated reduction of nitro and azido arenes to N-arylformamides using Zn-HCOONH4 is described. In the absence of microwave conditions, this methodology affords amines. This protocol has been extended to the synthesis of pyrrolo[2,1-c][1,4]benzodiazepines and 4(3H)-quinazolinones. (C) 2004 Elsevier Ltd. All rights reserved.

2-aminobenzoyl aminoacid hydrazide derivatives and quinazolinones derivatives was synthesized and fully characterized by IR, NMR, and elemental analysis. The activity of the prepared compounds on the growth of Leishmania aethiopica promastigotes was evaluated. 2-Benzoyl aminoacid hydrazide showed higher inhibitory effect than the quinazoline counterpart. The in vitro antipromastigote activity demonstrated

A series of quinazolinone amino acid ester and quinazolinone amino acid hydrazides were prepared under microwave irradiation as well as conventional condition. The microwave irradiation afforded the product in less reaction time, higher yield and purity. The structures of the synthesized compounds were confirmed by IR, NMR, and elemental analysis. The new synthesized compounds were studied for their
