A new method for introduction of indolylmethyl group to aldehydes or ketones using diethyl (o-isocyanophenylmethyl)phosphonate through Horner-Wadsworth-Emmons condensation, thiol-mediated radical cyclization, and the subsequent desulfurization is described. The Horner-Wadsworth-Emmons reagent was prepared from 2-nitrobenzaldehyde in a concise three-step sequence.
本文介绍了一种通过 Horner-Wadsworth-Emmons 缩合、硫醇介导的自由基环化以及随后的脱硫反应,使用(邻异氰酸苯甲基)膦酸二乙酯向醛或酮中引入吲哚甲基的新方法。Horner-Wadsworth-Emmons 试剂由 2-硝基苯甲醛通过简洁的三步顺序制备而成。
