  Enediyne- and Tributyltin Hydride-Mediated Aryl Radical Additions onto Various Radical Acceptors

  摘要：

  Tandem enediyne-radical cyclizations were carried out on substrates that contain nitrile and ketone radical accepters. The products of these cyclizations and the previously reported tandem enediyne-radical cyclizations containing aldehyde and oxime ether radical accepters were compared with tributyltin hydride-mediated aryl radical addition reactions with 1-bromonaphthalene derivatives containing aldehyde, oxime ether, nitrile, and ketone radical accepters, since these substrates go through similar initial radical intermediates. Although many of the same products were observed using either method of aryl radical generation, there were distinct differences in the product composition and identity depending on which method was used. These differences can probably be primarily attributed to the temperature difference of the two modes of radical generation.

  A dual gold(I)‐catalyzed three‐component reaction is developed to prepare indene‐fused carboxylic acid derivatives from diynes, alcohols, and pyridine N‐oxides in both inter‐ and intramolecular fashions. Pyridine N‐oxides exhibit unique reactivity and selectivity to oxidize the gold vinylidene. Experimental studies and DFT calculations support ketene formation as the key step.
