Herein, we describe the first example of copper-catalyzed oxidative thioamination maleimides with secondary amines and Bunte salts achievement C–N C–S bonds in a single flask. The protocol showcases prominently broad substrate scope is also efficient for late-stage modification an array pharmaceuticals. Preliminary mechanistic investigation indicates amination to form reactive enaminone subsequent intermolecular alkenyl C–H thiolation.
The first example of copper-catalyzed four-component coupling reaction aryl iodides, Se powder, secondary amines, and maleimides is developed. This provides an efficient concise route to access aminoarylselenated via double C–Se bonds C–N bond formation. appealing features this transformation are the use powder as a selenating reagent, green catalytic system, wide range substrate scope, late-stage selenation bioactive compounds.
Three-component amino- and carbotrideuteromethylthiolation of alkenes in water.
The first copper-catalyzed oxidative aminophosphorothiolation of maleimides with secondary alkylamines and diethylphosphorodithioate has been established.
An unprecedented copper-catalyzed oxidative aminohalogenation of electron-deficient maleimides with secondary amines and NXS (X = Cl, Br, I) was developed, in which the N-X bonds generated situ were used as difunctionalized reagents. The distinctive features this multicomponent reaction include a simple green catalytic system, spectral substrate range, late-stage modification drug molecules. Most importantly, umpolung radical cascade strategy exploits formation N-iodoamines that enable...
