α-methyl-β-hydroxy allylic esters has been developed that proceeds with high diastereoselectivity and provides products containing three contiguous stereogenic carbons, including a quaternary center. The potential utility of the rearrangement for complex molecule synthesis is also demonstrated.
开发了手性非外消旋 α-甲基-β-羟基烯丙酯的双离子爱尔兰-克莱森重排,该重排具有高非对映选择性,并提供含有三个连续立体碳(包括一个四级中心)的产品。还证明了重排对于复杂分子合成的潜在效用。
