摘要
In the palladium-catalyzed asymmetric substitution reaction between 1,3-diphenylallyl acetate and sodium salt of diethyl malonate, electron-withdrawing and electron-rich P-substituents in a single chiral back-bone give products of opposite stereochemistry. Sterically bulky substituents have the same effect as electron-rich ones.
