Only chiral anions do the job! Optically active gold complexes derived from substituted binol hydrogen phosphate catalyze the desymmetrizing cyclization of 1,4‐diynamides. This reaction provides access to synthetically useful, chiral methylene pyrrolidines with an all‐carbon‐substituted quaternary stereocenter.
只有手性阴离子才能完成这项工作!衍生自取代的磷酸氢二酚的光学活性金络合物催化1,4-二乙酰胺的去对称化环化反应。该反应可提供具有全碳取代的季立体中心的合成有用的手性亚甲基吡咯烷。
