A naturally occurring alkaloid aloperine was utilized as a chiral skeleton for the development of new ligands/catalysts in asymmetric synthesis. A number of N-substituted aloperines have been prepared, and a Pd-catalyzed asymmetric hydroarylation of ketimines using these chiral 1,3-diamine ligands was reported. A range of chiral sulfonyl amides were prepared in high yields and enantioselectivities
天然存在的生物碱 aloperine 被用作手性骨架,用于开发不对称合成中的新配体/催化剂。已经制备了许多 N-取代的 aloperines,并且报道了使用这些手性 1,3-二胺配体对酮亚胺进行 Pd 催化的不对称氢化芳基化。以高产率和对映选择性制备了一系列手性磺酰胺。已经研究了aloperines的立体选择性和结构关系。此外,对内消旋酸酐去对称化的初步研究也表明这些二胺在有机催化方面具有很好的潜力。这些发现将为受天然产物启发的手性配体设计和开发提供新的未来发展。
