diastereoselective method was developed for the [2,3]-sigmatropic rearrangement of N-allyl ammonium ylides, affording products in up to 95% isolated yields and up to 97:3 dr; most of the desired products were formed within 1 minute. For the asymmetric reaction, a chiral auxiliary was introduced to the starting compound, affording the rearrangement product with high diastereoselectivities. A rapid and diastereoselective
抽象的 开发了一种快速且非对映选择性的方法,用于N-烯丙基铵盐的[2,3]σ重排,可提供高达95%的分离产率和高达97:3 dr的产物。大多数所需的产品在1分钟内形成。对于不对称反应,将手性助剂引入起始化合物中,从而提供具有高非对映选择性的重排产物。 开发了一种快速且非对映选择性的方法,用于N-烯丙基铵盐的[2,3]σ重排,可提供高达95%的分离产率和高达97:3 dr的产物。大多数所需的产品在1分钟内形成。对于不对称反应,将手性助剂引入起始化合物中,从而提供具有高非对映选择性的重排产物。
