The straightforward design of a new library of chiral ligands (elpanphos) based on β-1,2-D-glucodiamine is described, which represents the enantiomeric counterpart of the naplephos library. In this guise, two representative ligands have been successfully applied in the Pd-catalyzed desymmetrization of meso-cyclopent-2-ene-1,4-diol, which leads to the expected enantiomer within short times and with
描述了基于 β-1,2-D-葡糖二胺的手性配体 (elpanphos) 新文库的直接设计,它代表了那不勒磷文库的对映体对应物。在这种伪装下,两种代表性配体已成功应用于 Pd 催化的 meso-cyclopent-2-ene-1,4-diol 的去对称化,从而在短时间内产生预期的对映异构体,并且在传统和非常规中均具有高 ee溶剂。
