A highly stereoselective aza-Henry reaction of α-aryl nitromethanes with aromatic N-Boc imines was established by using C1 -symmetric chiral ammonium betaine as a bifunctional organic base catalyst. Various substituted aryl groups for both imines and nitromethanes were tolerated in the reaction, and a series of precursors for the synthesis of unsymmetrical anti-1,2-diaryl ethylenediamines was provided.
通过使用C1对称手性铵甜菜碱作为双功能有机碱催化剂，建立了α-芳基硝基甲烷与芳香族N-Boc亚胺的高度立体选择性氮杂-Henry反应。该反应中，亚胺和硝基甲烷的各种取代芳基均能兼容，并提供了一系列用于合成不对称反式-1,2-二芳基乙二胺的前体。
