A visible-light photoinduced ringopening of N-alkyl-4-piperidinols under mild conditions has been achieved. The reaction sequence involves a visible-light-induced charge-transfer complex, which promoted the S–Cl bond cleavage of sulfonyl chlorides. The generated sulfonyl radical further reacts with N-alkyl-4-piperidinol cation radicals to achieve C–N and C–C bond cleavages to yield homoallylamine

Vinyl sulfones are privileged motifs known for their biological activity and synthetic utility. Synthetic transformations to efficiently access high-value compounds with these motifs are desired and sought after. Herein, a new procedure is described to form vinyl sulfone-containing compounds by selective functionalization of the C(sp3)–H bond adjacent to the pyridine ring of pharmacologically prevalent
