Asymmetric amplification in nickel-catalyzed conjugate addition to chalcone
摘要:
Nickel complexes with optically active pyridine ligands catalyze the conjugate addition of diethyl zinc to chalcone. This catalytic alkylation gives products with ee's of up to 86%. Strong asymmetric amplification has been observed using ligands of low optical purity.
