Interaction of ethyl 2-amino-4,5,6, 7-tetrahydrobenzo[b]thiophene-3-carboxylate 1 with 2-thiophene carbonyl chloride 2 afforded ethyl 2-(2-thenoylamino)-4, 5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate 3 which upon cyclization yielded 2-(2-thienyl)-5,6,7, 8-tetrahydrobenzo[b]-thieno[2,3-d]-4H-3, 1-oxazin-4-one 4 and 2(2-thienyl)-3-amino-5, 6,7,8-tetrahydrobenzo-[b]thieno[2,3-d]-3,4-dihydropyrimidin-4-one 6. Some of the prepared compounds were screened for their antiinflammatory activity, compound...
