Abstract
A visible-light photoinduced ring opening 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 products.
