摘要
Complexes of BINOL-based ligands with Zr((OBu)-Bu-t)(4) catalyze the Friedel-Crafts alkylation reaction of indoles and pyrrole with nonchelating beta-substituted alpha,beta-enones at room temperature affording the expected products with good yields and ee above 95% in most of the studied examples.
