cascade reaction of 2,3-diketoesters, aromatic amines, and 1,3-cyclohexanediones has been developed for the highly enantioselective synthesis of axially chiral N-arylindoles. The success of this method derives from the use of a newly developed second-generation chiral spirocyclic phosphoric acid as the catalyst. In addition, this protocol was extended to the synthesis of an axially chiral monophosphorus
已经开发了有效的有机催化的对映体选择性的三组分级联反应的2,3-二酮酸酯,芳族胺和1,3-环己二酮,用于轴向手性N-芳基吲哚的高对映选择性合成。该方法的成功源于使用新开发的第二代手性螺环磷酸作为催化剂。另外,该方案扩展到轴向手性单磷配体的合成。
