One‐Pot synthesis of isothiachromene,isochromene, isoquinoline and tetrahydronaphthalene derivatives

A new series of tetrahydronaphthalene, isothiachromene, isochromene and isoquinoline derivatives were synthesized by reacting cyclohexylidenemalononitrile with active nitriles, active halo compounds, carbon disulfide, aldehydes, isothiocyanates and isocyanates, respectively.
