monodentate phosphite- and phosphine-type ligands in the Ir-catalyzed asymmetric direct reductive amination of 2,3,4,9-tetrahydro-1H-сarbozol-1-ones was carried out. A positive effect of the use in the reaction of a mixture of chiral and achiral ligands was demonstrated. This approach makes feasible a one-pot synthesis of valuable biologically active compounds of (tetrahydro-1H-carbazol-1-yl)amine series
在 Ir 催化的 2,3,4,9-四氢-1H-咔唑-1-酮的不对称直接还原胺化中,手性和非手性单齿亚磷酸酯和膦型配体的均质和杂合组合的复杂催化剂的比较测试进行了。证明了在手性和非手性配体的混合物反应中使用的积极效果。这种方法使得(四氢-1H-咔唑-1-基)胺系列有价值的生物活性化合物的一锅合成成为可能。
