alkylation of indoles with allylicalcohols has been developed. Catalyzed by sulfuric acid (10 mol-%), the reaction between indoles 2 and allylicalcohols 1 based on ketene dithioacetal affords polyfunctionalized indoles 3 in good to excellent yields with high regioselectivities under mild conditions. The catalytic carbon-carbon coupling reaction provides a facile method for the environmentally benign
