    • Abstract


      Syntheses of 3-(phenyl)-benzo[b]thiophene [2, 3-d][1,2] benzodiazocine derivatives have been accomplished by the reaction of 3-phenacylidine-2-benzo[b]thiophene-2-ones with o-phenylene diamine. The photolytic reaction with trans-stilbene resulted in the exclusive formation of spiro{2',5',6'-triphenyl-2H-pyran-4',3}-benzo[b]thiophene-2-one derivatives. Theoretical calculations have been performed to study the mechanism and stereoselectivity of products. Good yield and broad scope of usable substrates of industrial relevance are other prominent features of the present methodologies.
