reductive Ireland–Claisen rearrangement through borane‐mediated hydrosilylation is reported. The method employs a borane catalyst with a special structural design and affords access to synthetically relevant products with high diastereoselectivity. Depending on electronic and structural parameters, the reaction can be coupled with a 1,3‐allylic shift, thus the valence isomer of the Ireland–Claisen product
据报道,通过硼烷介导的氢化硅烷化使爱尔兰-克莱森还原性重排。该方法使用具有特殊结构设计的硼烷催化剂,并提供具有高非对映选择性的合成相关产物。根据电子和结构参数,反应可以与1,3-烯丙基位移耦合,从而形成爱尔兰-克莱森产品的价异构体。
