Abstract

In(OTf)(3) was found to be a useful Lewis acid catalyst for direct alkylative Passerini reaction of aldehydes, isocyanides, and free aliphatic alcohols. In the present reaction, aromatic and alpha,beta-unsaturated aldehydes performed as nice substrates to give the corresponding alpha-alkoxy amide products in good yield.

摘要

发现三(三氟甲磺酰)铟是醛、异腈和游离脂肪醇直接烷基化Passerini反应的有效路易斯酸催化剂。在本反应中,芳香醛和α,β-不饱和醛是良好的底物,能以良好的产率得到相应的α-烷氧基酰胺产物。
