Asymmetric dihydroxylation of β,β′‐ disubstituted enamides afforded chiral tertiary‐alcohol‐containing α‐hydroxyaldehydes and 1,2‐diols with high enantioselectivity (see scheme). This method was applied to the total synthesis of the antifungal natural product (+)‐tanikolide, as well as the synthesis of an intermediate en route to (S)‐oxybutynin.
β,β'-二取代酰胺的不对称二羟基化提供了具有高对映选择性的手性含叔醇的α-羟醛和1,2-二醇(参见方案)。该方法适用于抗真菌天然产物(+)-tanikolide的全合成,以及在(S)-奥昔布宁途中的中间体的合成。
