A simple and efficient visible‐light‐initiatedcascadereaction of 2‐isothiocyanatonaphthalenes and amines with ambient dioxygen as the sole oxidant underadditive‐, externalphotocatalyst‐free and ambient conditions was developed. 38 Examples of N‐substituted naphtho[2,1‐d]thiazol‐2‐amines were regioselectively constructed in good to excellent yields.
在无添加剂,无外部光催化剂的条件下和环境条件下,开发了一种简单而有效的由可见光引发的2-异硫氰基萘和胺与环境双氧作为唯一氧化剂的级联反应。38区域选择性地构建了N-取代的萘并[ 2,1- d ]噻唑-2-胺实例。

An efficientsynthesis of new 2-aminothiazole-annulated compounds is described via copper(II) triflate promoted sequential condensation, arylation, and heterocyclization reactions in one step. The reaction is compatible with a variety of substrates providing efficient access to many biologically important skeletons in good yields. copper triflate -multicomponent reaction - naphthothiazole - domino
