reported a copper-catalyzed vinylamination of S-alkylisothiouronium salts with maleimide and organic amines with the assistance of FeCl3, enabling the preparation of structurally diverse aminoalkylthiolated maleimides and applying them to late-stage modification of pharmaceuticals. Importantly, this strategy makes it possible to introduce the SCD3 functional group into the maleimide skeleton by using the

copper-catalyzed oxidativecarboamination of maleimides with alkyl amines and α-bromo carboxylates is described. These multicomponent reactions show good functional group compatibility and are suitable for the late-stage modification of a series of neuroprotective agents, providing a direct path for the library synthesis of 3-carbo-4-amino maleimides. The initial copper-catalyzed oxidative amination of
Alkyltin fluoride is a frequently used electrophilic stannylation reagent via the cleavage of the Sn–F bond in traditional organic synthetic chemistry. Herein, we report the unprecedented copper-catalyzed aminoalkylation of maleimides using alkyltin fluoride as alkylating reagent through cleavage of the C–Sn bond via a radical pathway. Excellent functional group tolerance, use of O2 as green oxidant

A meaningful copper-catalyzed chemo-selective oxidative alkylamination of maleimides with secondary alkyl amines and simple alkanes has been developed. This transformation exhibits excellent compatibility with an array of polyfunctionalized organic amines and inactivated alkanes, modular synthesis of 3-carbo-4-amino maleimides under simple, and efficient catalytic systems.
