  Radical cyclization of (bromomethyl)dimethylsilyl propargyl ethers. Regio-, chemo- and stereoselectivity.

  摘要：

  Radical cyclization of (bromomethyl)dimethylsilyl propargyl ether derivatives 1 is a powerful reaction with a high degree of regio-, chemo-, and stereoselectivity. Trisubstituted olefins 3, cyclopentene derivatives 5, and diquinane system 7j are obtained in good yields by a judicious choice of unsaturated substituents. Triquinane frameworks could be obtained stereoselectively from a suitable acyclic substrate of type 1 in a one-pot reaction. First attempts have not yet allowed us to aim at this goal due to interesting (1,5) hydrogen transfers. Moreover, we have intercepted, for the first time, the alpha-cyclopropyl radical which is involved in the Stork-Beckwith mechanism of the 5-versus 6-membered ring formation in the vinyl radical cyclization.

  Vinyl radical intermediates generated from radical cyclization of (bromomethyl)dimethylsilyl propargyl ethers have been trapped intramolecularly by a double bond leading to functionalized carbocycles with high yield and high regiosclectivity.

  日期：1997.10

  The scope and limitations in the 1,n (n = 5, 6, 7) hydrogen transfers from homoallyl radicals of type 10 have been delineated. Encouraging results have notably been obtained with a dioxolane on the side chain to promote a 1,6-H transfer and with a TBS ether to promote a 1,5-H transfer. (C) 1997 Elsevier Science Ltd.
