One-pot sulfa-Michael addition reactions of disulfides using a pyridine-borane complex under blue light irradiation

摘要

We report a one-pot sulfa-Michael addition reaction using a disulfide and a pyridine-borane complex under blue light irradiation.This novel synthetic approach has a broad substrate scope and a high functional group tolerance.Mechanistic studies suggest that sequential radical and ionic processes provide a practical solution for constructing carbon-sulfur bonds.
