摘要：
Reactions of ethylmagnesium bromide with benzaldehyde and acetophenone in toluene proceed stereoselectively in the presence of catalytic amounts of chiral podands and crown ethers. Under catalytic conditions theyield of the corresponding alcohols is nearly quantitative. The optical yield varies in the range 9-86% depending
