摘要
Chiral [AI(salen)Cl] complex (10 mol%) in the presence of 2,6-lutidine (10 mol%) was found to be effective in catalysing the enantioselective Friedel-Crafts-type conjugate addition of indoles (3) to (E)-arylcrotyl ketones (2), furnishing the corresponding P-indolyl ketones in excellent yield and high en antioselectivity (ee up to 89%).
