This process was used to promote sulfonylative and azidosulfonylative cyclizations of enynes to give several classes of highly functionalized heterocycles. The use of THF as the solvent is critical for successful reactions. The proposed mechanism of radical initiation involves the photosensitized formation of a triplet sulfonyl nitrene, which abstracts a hydrogen atom from THF to give a tetrahydrofuran-2-yl radical, which then reacts with the sulfonyl azide to generate the sulfonyl radical.}, doi = {10.1002/chem.201704380}, eissn = {1521-3765}, issn = {0947-6539}, issue = {69}, journal = {Chemistry - A European Journal}, note = {AAM of article published.
