An efficient one-step synthetic strategy was used to prepare a set of dicarboxamides through palladium-catalysed amino carbonylation of iodoalkenyl and iodoaryl compounds, with use of various alkyl- and aryldiamines as N-nucleophiles. The isolated yields of the dicarboxamides depended signifi cantly on the iodo substrate and diamine structures, as well as on the reaction conditions, the best one (ca
使用一种有效的一步合成策略,通过钯催化的碘代烯基和碘代芳基化合物的氨基羰基化,使用各种烷基和芳基二胺作为 N-亲核试剂,制备一组二甲酰胺。二甲酰胺的分离产率在很大程度上取决于碘底物和二胺结构以及反应条件,最好的产率(约 70%)以 1-碘环己烯为底物和 1,4-二氨基丁烷为底物亲核试剂,在 100 °C 和 30 bar CO。当使用碘苯作为模型芳基卤时,目标二苯甲酰胺的最高产率(约 65%)以 1,4-二氨基苯作为偶联胺,在 100 ° C 和 10 bar 的 CO。关于它们对人肺癌 A549 细胞的体外细胞毒性的初步研究显示 N,N -(丁烷-1,
