摘要：

A highly efficient synthetic strategy toward Michael addition of indoles to alpha,beta-unsaturated esters has been developed using Lewis acid InBr3 as catalyst. The reactions generated 3-substituted indoles in high yields with excellent regio-selectivity in the presence of catalytic amount of InBr3 under mild reaction conditions. The method is simple, efficient and practical.
