Enantioselective conjugate addition of diethylzinc to enones using chiral β-aminoalcohol as chiral catalyst or ligand
摘要:
Optically active beta-substituted ketones of up to 94% e.e. were synthesized by the enantioselective conjugate addition of diethylzinc to enones in the presence of either a catalytic or stoichiometric amount of chiral beta-aminoalcohol.
