Abstract

Reaction of 2-benzylidene-1-benzocyclanones 1 with dithiocarbamic acid afforded open-chain addition products 2A-4B. Dehydration of the adducts yielded tricyclic 1,3-thiazine-2-thiones 5 and 6. Treatment of 1 with thiourea under acid conditions gave tricyclic 2-amino-1,3-thiazines 7-9. IR and1H NMR spectroscopic investigations showed 7-9 to exist predominantly in the amino tautomeric form both in the solid state and in solution.
