  Synthetic studies of the tandem enediyne-mono- and bisradical cyclizations

  摘要：

  The readily synthesized enediynes 12a-j possessing a tethered olefin radical acceptor can participate in a tandem enediyne-radical cyclization to yield dibydrobenzindene derivatives 14a-j. In the present study, the scope of this reaction was expanded to include a wide variety of olefin acceptors. Substitution at both ends of olefin leads to the formation of two diastereomers 14b and 14c in a 3.5:1 ratio when R3 is Me and R2 is CO2Me. The structures of the dihydrobenzindene products 14b and 14c were confirmed by generating a radical from 25 by a tributyltin hydride reaction which undergoes radical cyclization; this radical is similar to the enediyne-generated radical, which also cyclizes. It was shown that, in 14i and 14j, a substituent at R1 slowed the reaction but still resulted in a good to excellent yield of product. A tandem enediyne-6-exo-radical cyclization of 16 was also carried out but did not work as well as its 5-exo counterpart 12a. Finally, an enediyne 33 containing two olefinic tethers was cyclized in a process to form tetracycle 34 where three rings were formed in one synthetic operation.

  Molecular switches based on helical tetrasubstituted alkenes, substituted with either electron‐withdrawing (CF3, F, CN; 2 a–c, 3 a,c) or ‐donating substituents (Me, OMe; 2 d,e), have been synthesized from acyclic precursors 4 and 5 in a domino carbopalladation/Stille reaction. This palladium‐catalyzed process allowed the rapid assembly of two CC bonds, two six‐membered rings, and the tetrasubstituted

  New photochromic switches based on helical alkenes can quickly and efficiently be accessed by Pd-catalyzed domino reactions using a modular approach; this allows a wide variability in product formation with the advantages of a convergent synthetic route. The alkenes have been synthesized in excellent enantioselectivity and their switching properties assessed by stimulation with nanosecond laser pulses

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

  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.
