The first example of copper-catalyzed four-component coupling reaction of aryl iodides, Se powder, secondary amines, and maleimides is developed. This reaction provides an efficient and concise route to access aminoarylselenated maleimides via double C–Se bonds and C–N bond formation. The appealing features of this transformation are the use of Se powder as a selenating reagent, a green catalytic system
the first example of copper-catalyzed oxidative thioamination of maleimides with secondary amines and Bunte salts with the achievement of C-N and C-S bonds in a single flask. The protocol showcases a prominently broad substrate scope and is also efficient for the late-stage modification of an array of pharmaceuticals. Preliminary mechanistic investigation indicates copper-catalyzed oxidative amination

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
