Selective H transfer by ABC: A new asymmetric binary acid catalyst was developed to promote 1,5-H transfer specifically and stereoselectively in tert-aminocyclization reactions with excellent activity, high enantioselectivity, and broad substrate scope. The H atom (in red) was proven to transfer through a stereospecific suprafacial pathway (see scheme).
ABC 通过 H 原子转移:开发了一种新型不对称双酸催化剂,可在叔胺环化反应中通过立体特异性和立体选择性地促进 1,5-H 原子转移,具有优异的活性、高对映选择性和广泛的底物范围。证明 H 原子(用红色表示)通过立体特异性的超分子途径转移(见方案)。
