Abstract

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.
