Yg. Zhou et al., Fructose derived pyridyl alcohol ligands: synthesis and application in theasymmetric diethylzinc addition to aldehydes, CHIN J CHEM, 18(1), 2000, pp. 121-123
Easily available chiral ketones were employed for the synthesis of opticall
y active pyridyl alcohols, which were applied in the asymmetric diethylzinc
addition to aldehydes, up to 89.4% e. e. was obtained using D-fructose-der
ived pyridyl alcohol.
