Following our previous mechanistic studies of multicomponent Ugi-type reactions, theoretical calculations have been performed to predict the efficiency of new substrates in Ugi-Smiles couplings. First, as predicted, 2,4,6-trichlorophenol experimentally gave the corresponding aryl-imidate. Theoretical predictions of nitrosophenols as good acidic partners were then successfully confirmed by experiments. In the latter case, the reaction offers a new access to benzimidazoles.
基于我们之前对多组分Ugi型反应的机理研究，已进行理论计算以预测新型底物在Ugi-Smiles偶联反应中的效率。首先，如预测的那样，2,4,6-三氯苯酚通过实验得到了相应的芳基亚氨酸酯。亚硝基苯酚作为良好酸性伙伴的理论预测随后通过实验得到成功证实。在后一种情况下，该反应为苯并咪唑提供了一种新的合成方法。
