Eleven-membered ring enediyne 1, which incorporates an α-diazo-β-diketone moiety, undergoes efficient light-induced ring contraction to produce two isomeric ten-membered ring enediyne compounds. The latter undergo spontaneous facile Bergman cyclization at
Synthetic studies of the tandem enediyne-mono- and bis-radical cyclizations

, p. 11744 - 11752 (2007/10/02)
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
