rearrangement of (E)-allylic trichloroacetimidates to provide transposed allylic trichloroacetamides of high enantiopurity, a transformation that underlies the first truly practical method for transforming prochiral allylic alcohols to enantioenriched allylic amines and congeners. The high functional group compatibility of this asymmetric rearrangement and the demonstrated broad utility in synthesis of the allylic
COP-Cl 催化 (E)-烯丙基三氯乙酰亚胺酯的重排以提供高对映体纯度的转位烯丙基三氯乙酰胺,这种转化是将前手性烯丙醇转化为富含对映体的烯丙基胺和同系物的第一个真正实用的方法的基础。这种不对称重排的高官能团兼容性以及在烯丙基三氯乙亚氨酸酯到烯丙基三氯乙酰胺转化的合成中表现出的广泛用途是这种新的催化不对称反应的独特特征。
