A highly stereoselective procedure for the preparation of a variety of syn 2-amino alcohol derivatives from enantiopure E-γ-hydroxy-α,β-unsaturated phenyl sulfones is described. The method is based on an intramolecular carbamate cyclization, followed by functionalization at α-position by reaction of the sulfonyl carbanion with electrophiles, and subsequent elimination of the sulfonyl group.
描述了从对映体纯的E-γ-羟基-α,β-不饱和苯基砜制备各种合成的2-氨基醇衍生物的高度立体选择性的方法。该方法基于分子内氨基甲酸酯环化,然后通过磺酰基碳负离子与亲电试剂的反应在α-位官能化,然后消除磺酰基。
