Abstract
A remarkable Pd-catalyzed diamination of unactivated alkenes using N-fluorobenzenesulfonimide (NFBS) as an aminating reagent is described. The reaction incorporates one nitrogen donor from the substrate and the other from the NFBS, thereby generating cyclic diamine derivatives in a single step. The products are differentially protected at both nitrogens, allowing for maximal synthetic flexibility.
