((S)-1-(1,3,5-trimethyl)benzylpyrrolidin-2-yl)diphenylmethanol (1d) was found to be an effective chiral ligand
in the asymmetric transfer reaction of phenyl to aldehydes to give the corresponding adducts in excellent enantioselectivity
(up to 98% ee) with very high yields (up to 99%).
Keywords: Tertiary amino alcohol, transfer reaction, phenylboronic acid, diethyl zinc, diarylmethanols.
