It's a SnAP! The transformation of aldehydes into N‐unsubstituted 3‐thiomorpholines provides a convenient alternative to metal‐catalyzed cross‐coupling reactions, which are generally unsuited to the functionalization of saturated N‐heterocycles. A copper‐mediated radical cyclization is the key to the mild conditions, high functional group tolerance, and broad substrate scope offered by these reagents
