AbstractThe reactive intermediate generated by the reaction of alkyl isocyanides and dialkyl acetylenedicarboxylates was trapped by ethyl carbazones to produce stable ketenimine derivatives in good yield. The reaction is characterized by mild conditions, high selectivity, and tolerance to various functional groups. Graphical abstract
摘要由烷基异氰化物和乙炔二羧酸二烷基酯反应生成的反应性中间体被乙基氨基甲酸乙酯截留,从而以高收率生产出稳定的酮亚胺衍生物。该反应的特征在于温和的条件,高的选择性和对各种官能团的耐受性。 图形概要
