Synthetic studies of the tandem enediyne-mono- and bis-radical cyclizations

Article abstract of DOI:10.1021/ja00078a013

The readily synthesized enediynes 12a-j possessing a tethered olefin radical acceptor can participate in a tandem enediyne-radical cyclization to yield dihydrobenzindene derivatives 14a-j. In the present study, the scope of this reaction was expanded to i
