We herein describe a chiral diboron-templated highly diastereoselective and enantioselective reductive coupling of isoquinolines that provided expedited access to a series of chiral substituted bisisoquinolines in good yields and excellent ee’s under mild conditions. The method enjoys a broad substrate scope and good functional group compatibility. Mechanistic investigation suggests the reaction proceeds
我们在本文中描述了异喹啉的手性二硼烷模板化的高度非对映选择性和对映选择性还原偶联,其在温和条件下以良好的产率和优异的ee提供了快速获得一系列手性取代的双异喹啉的途径。该方法具有广泛的底物范围和良好的官能团相容性。机理研究表明,该反应通过协同的[3,3]-σ重排而进行。
