The Michael addition of indoles to α,β-unsaturated carbonyl compounds is an extremely popular way to produce indolyl-substituted ketones. Herein, a mild, visible-light-promoted Michael addition of indoles to chalcones (or other 3-aryl enones) is described, taking advantage the use of arylazo sulfones as the photoacid generator (PAG) in low catalyst loading and 427 nm as the irradiation source.
吲哚与 α,β-不饱和羰基化合物的迈克尔加成是生产吲哚基取代酮的一种非常流行的方法。本文描述了吲哚与查尔酮(或其他 3-芳基烯酮)的温和、可见光促进的迈克尔加成反应,利用芳基偶氮砜作为低催化剂负载量的光致产酸剂(PAG),并以 427 nm 为光源。辐照源。
