Simple synthesis of 7-amino-4,5-dihydrobenzo[f][1,4]oxazepin-3-ones
A simple method for the synthesis of 7-amino-4,5-dihydro-benzo[f][1,4] oxazepin-3-ones from 5-nitrobenzaldehydes and 2-haloesters was described. The three-step procedure involves the synthesis of methyl 2-(2-formyl-4- nitrophenoxy)alkanoates, followed by
