Olefin Difunctionalization for the Synthesis of Tetrahydroisoquinoline, Morpholine, Piperazine, and Azepane.

This report outlines a versatile strategy for synthesizing a diverse array of N-heterocycles. By the utilization of common olefins, this simple protocol facilitates their coupling with various bifunctional reagents. Furthermore, it can be integrated with C-H amination techniques to directly produce N-heterocycles in a multicomponent cascade coupling process. The unique bond disconnection logic employed in this process underscores its efficiency in achieving rapid simplification through cascade couplings.
