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‐nitrophe

Novel 1-(3-benzofuranyl)-2-phcnylethanones 4a-d have been prepared by acetylation of 2-alkylbenzo-furans 2a-c with phenylacetyl chlorides 3a-b. The methoxy derivatives 4b-d have been demethylated to the corresponding phenols 5b-d with pyridinium hydr
