Synthetically versatile alkyl sulfinates RSO2R1 (R = cyclobutyl, Bn, pyridin-2-ylmethyl, etc.; R1 = F, 2-(tert-butoxy)-2-oxoethyl, Ph, Bn, etc.) can be prepared from readily available amines RNH2, using Katritzky pyridinium salt intermediates I. In a catalyst-free procedure, primary, secondary, and benzylic alkyl radicals are generated by photoinduced or thermally induced single-electron transfer (SET) from an electron donor-acceptor (EDA) complex, and trapped by SO2 to generate sulfonyl radicals. Hydrogen atom transfer (HAT) from Hantzsch ester gives alkyl sulfinate products, which are used to prepare a selection of medicinal chem. relevant sulfonyl-containing motifs.
