Mechanochemical synthesis of 3-substituted 2-indolymethanols through scandium(Ⅲ)/palladium(Ⅱ) synergistic catalyzed Friedel-Crafts alkylations of donor-acceptor cyclopropanes and 2-indolymethanols has been developed. A wide broad of 3-substituted 2-indolymethanols have been afforded in moderate to excellent yields. This strategy has the advantage of short reaction time, wide substrate scope, mild reaction conditions, and so on. The synthetic utility was further demonstrated by gram-scale reaction and derivatization of the desired product.
