Herein, we report a mild and efficient hydroxymethylation of quinolines via an iron promoted cross-dehydrogenative coupling reaction under external acid free conditions. Various hydroxyalkyl substituted quinolines were achieved in excellent yields with well tolerated functional groups. Importantly, a few of the hydroxylmethylated quinolines were further transformed into respective aldehydes, and were
在本文中,我们报告了在外部无酸条件下,通过铁促进的交叉脱氢偶联反应,喹啉的温和有效羟甲基化。各种羟基烷基取代的喹啉以良好的收率得到了良好的耐受性。重要的是,一些羟甲基化喹啉被进一步转化成各自的醛,并成功地用于生物碱arsindoline-A及其衍生物的合成。
