catalytic enantioselectiveFriedel-Craftsalkylation of indoles with aromatic α,β-unsaturatedaldehydes has been developed. The process is promoted by (S)-diphenylprolinol trimethyl silyl ether to afford, after sodium borohydride mediated reduction, 3-indolyl-3-phenylpropanols in high enantioselectivities and good yields. organocatalysis - enantioselectivity - Friedel-Craftsalkylation - indoles - aromatic
