Twice as good: The title reaction using the tryptophan‐derived bifunctional organic catalyst 1 has been developed. The reported method led to the synthesis of chiral γ‐substituted butenolides in excellent yields, with high diastereo‐ and enantioselectivities. Facile synthesis of chiral glycerol derivatives containing a tertiary hydroxy group has also been demonstrated.
两次一样好:使用色氨酸衍生的双官能有机催化剂1进行了标题反应。报道的方法导致以高收率,高非对映选择性和对映选择性选择性合成手性γ-取代的丁烯内酯。还已经证明了容易合成含有叔羟基的手性甘油衍生物。
