Article

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.

Keywords

2-acyl(aroyl)benzo[b]thiophene-3-acetic acids 1-aryl-3,4-dihydro-5H-benzothieno[2,3-d]-[1,2]diazepin-4-ones hydrazine hydrate cyclization
