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.

The title compound (3a) was prepared by the reaction of 2-benzoylbenzothiophen-3(2H)-one 1,1-dioxide (1) with tetraphosphorus decasulphide, acetonitrile, and sodium hydrogen carbonate.The structure was confirmed by an alternative synthesis from ethyl 3-benzothienylacetate.The isomeric 4-phenyl-2H-thiopyranobenzothiophen-2-thione 5,5-dioxide (2a) and a number of analogues of (3a) and (2a) were prepared.
