An efficient and practical method for the synthesis of indolyl-nitroalkane derivatives catalyzed by N-bromosuccinimide is described. The generality of this method was demonstrated by synthesizing an array of diverse 3-substituted indole derivatives by the reaction of different β-nitrostyrenes with various substituted indoles. Simple reaction conditions accompanied by good yields of indolyl-nitroalkanes are the merits of this methodology.

The 1,4-conjugate addition of indoles to nitroolefins was efficiently carried out in aqueous media using baker’s yeast as a biocatalyst at room temperature. The merits of the present method are operational simplicity, easy workup, utilization of an inexpensive catalyst, free from hazardous organic solvents and good yields of products. The generality of this method was demonstrated by synthesizing an
