Weng, Jian-Quan published the artcileEnantioselective Friedel-Crafts Alkylation Reactions of 3-Substituted Indoles with Electron-Deficient Alkenes, Synthetic Route of 4230-93-7, the publication is Journal of Organic Chemistry (2016), 81(7), 3023-3030, database is CAplus and MEDLINE.
Highly enantioselective Friedel-Crafts C2-alkylation reactions of 3-substituted indoles with ¦Á,¦Â-unsaturated esters and nitroalkenes were developed using chiral Lewis acids as catalysts, which afforded chiral indole derivatives bearing C2-benzylic stereogenic centers in good to excellent yields (up to 99%) and enantioselectivities (up to 96% ee).
