Abstract

An easy, highly efficient, and simple one-pot approach for the synthesis of dihyroindeno[1,2-b]pyrroles and indeno[2′,1′:4,5]pyrrolo[1,2-a]-fused 1,3-diazaheterocycles under mild conditions is reported. The reaction of a primary amine or 1,n-diamine with 1,1-bis(methylthio)-2-nitroethene in the presence of ninhydrin in aqueous media afforded the title compounds in good yields.
