A visible-light mediated three-component radical process using dithiocarbamate anion catalysis

A three-component radical process is reported that, by coupling alkyl chlorides, maleimides, and heteroaromatic fragments, installs multiple biologically relevant heterocycles within complex cascade products. This method, which generates radicals via an SN2-based photochemical catalytic mechanism, activates substrates incompatible with or inert to classical radical-generating strategies.
