Abstract

Abstract Treatment of 5-methylthio-2, 3-dihydrothieno [3, 2-f]-1, 4-thiazepine (9) with acylhydrazines gave 5, 6-dihydrothieno [3, 2-f]-1, 2, 4-triazolo [4, 3-d][1, 4] thiazepines 10, 11, and that of 9 with ethyl anthranilate gave 5, 6-dihydrothieno [3′, 2′: 6, 7][1, 4] thiazepino [5, 4-b] quinazolin-8-one (14). Reaction of 9 with hydrazine hydrate or 4- chlorophenylhydrazine afforded 5-hydrazino compounds 12, 15, which were ...
