摘要：

Asymmetric Michael-type Friedel-Crafts (F-C) alkylations of indoles with nitroolefins catalyzed by a chiral H-8-BINOL-based phosphoric acid were investigated. The reactions took place very smoothly in the presence of only 5 mol-% of catalyst at room temperature to afford the desired F-C alkylation products in good yields and with moderate enantioselectivities.
