Abstract
Grignard reagents were added to 2,2-disubstituted 1,3-oxazolidines and enolizable ketimines prepared from hydroxyacetone and phenylglycinol derivatives, with high to excellent diastereoselectivity, to yield 2,2-disubstituted 1,2-amino alcohol derivatives. Lewis acids had considerable influence on the yield and diastereoselectivity of the addition. This method was applied to the first asymmetric synthesis of the 5-HT reuptake inhibitor Cericlamine.
