Enantiomerically enriched trans-2,3-epoxyamides 3 were prepared by the reaction of aldehydes 2 with camphor-derived chiral sulfonium ylide 1 in good yields and moderate to good ee values. The absolute configuration of the reaction product is also determined by chemical transformations.
通过醛2与樟脑衍生的手性sulf叶立德1的反应,可以以良好的收率和中等至良好的ee值制备对映体富集的反式-2,3-环氧酰胺3。反应产物的绝对构型也通过化学转化来确定。
