Asymmetric transfer hydrogenation (ATH) of acyclic imines has been rarely reported by using Ru-based catalysts. In this manuscript, employing Ru-catalysts with minimal stereogenicity in combination with formic acid/triethylamine as the hydrogen donor enables a highly efficient ATH of N-diphenylphosphinyl acyclic imines. These substrates that include various aryl alkyl and heteroaryl alkyl substituted imines
使用 Ru 基催化剂很少报道无环亚胺的不对称转移氢化 (ATH)。在这份手稿中,使用具有最小立体异构性的 Ru 催化剂与甲酸/三乙胺作为氢供体相结合,可以实现N-二苯基膦基无环亚胺的高效 ATH 。这些包含各种芳基烷基和杂芳基烷基取代亚胺的底物都与该催化体系相容,并以优异的对映体过量 (ee's) 和产率获得相应的还原胺。
