Condensed Diazepines. Synthesis of 1-R-3,4-Dihydro-5H-Benzothieno[2,3-d][1,2]Diazepin-4-Ones

Novel 1-R-3,4-dihydro-5H-benzothieno[2,3-d][1,2]diazepin-4-ones have been prepared by the cyclization of 2-acyl(aroyl)benzo[b]thiophene-3-acetic acids or 1-R-benzothieno[2,3-c]pyr-3-ones with hydrazine hydrate.
