A highly enantioselective synthesis of substituted tetrahydrocarbolines via Ir-catalyzed Friedel–Crafts type intramolecular asymmetric allylic alkylation of 2-indolyl allyl carbonates has been developed. This strategy features excellent chemoselectivity and enantioselectivity, mild reaction conditions, and an easily accessed chiral ligand.
已经开发了通过对二吲哚基烯丙基碳酸酯进行Ir催化的Friedel-Crafts型分子内不对称烯丙基烷基化反应来高度取代苯四甲酸的对映体合成反应。该策略具有出色的化学选择性和对映选择性,温和的反应条件以及易于使用的手性配体。
