Abstract
2,3-Dihydronaphtho [1,2-b] thiophenes (2, 4, 5, and 7) and naphtho [1,2-b] thiophenes (3 and 8) bearing trifluoromethyl groups were easily synthesized by aromatic nucleophilic nitrogen-sulfur exchange reaction of N,N-dimethyl-2,4-bis(trifluoroacetyl)-1-naphthylamine (1) with thioglycolic acids and with benzyl mercaptan, followed by cyclization (cyclodehydration)
