Regioselectivity of heterocyclization of 2-substituted 3,3-bis(methylsulfanyl)acrylo-nitriles with 2-benzimidazoleacetonitrile
摘要:
Functionalized pyrido[1,2-a]benzimidazoles have been synthesized by the interaction of 2-substituted 2-cyano-3,3-bis(methylsulfanyl)acrylonitriles with 2-benzimidazoleacetonitrile under S(N)Vin reaction conditions.
