RESUMO
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 beta-nitrostyrenes with various substituted indoles. Simple reaction conditions accompanied by good yields of indolyl-nitroalkanes are the merits of this methodology.

The diastereoselective synthesis of trans-endo-decahydroquinolin-4-one (4) via a three-component reaction of aldehydes (1), anilines (2), and 1-acetylcyclohexene (3) in the presence of iodine in a one-pot reaction at room temperature is described. The short reaction time, easy workup, excellent yield, and mild reaction conditions make this novel annulation strategy both practical and attractive.
