has significantly improved the accessibility of various cyclo-propylamines. Except in a few cases, however, this methodhas the drawback of yielding 2-substituted cyclopropyl-amines with only low or moderate degrees of diastereoselec-tivity. In contrast, the corresponding titanium-mediatedtransformation of esters into cyclopropanols yielded
显着提高了各种环丙胺的可及性。然而,除了少数情况外,该方法的缺点是产生仅具有低或中度非对映选择性的 2-取代环丙胺。相比之下,相应的钛介导的酯向环丙醇的转化产生了
