3,3_-Bis(isopropylsulfanyl)-5,5_-bi-1,2,4-triazine 2 is easily transformed into annulated 2,2_-bipyridines 4 and 6 with fused cycloalkene rings via [4+2]cycloaddition/retro cycloaddition reaction with cyclic enamines 3a-d. Oxidation of 4 and 6 with potassium permanganate under phase transfer catalysis conditions provided a series of the corresponding sulfonyl derivatives 7 and 8.
