    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.

  • Radical cyclization of bromomethyldimethylsilyl propargyl ethers—VIII. Bimolecular stereoselective hydrogen abstraction by trisubstituted vinyl radicals. A new example of rare (1,4) hydrogen transfer.

    Experiments with Bu3SnD show that trisubstituted vinyl radicals 2 abstract hydrogen bimolecularly from tin hydride. A high degree of stereoselectivity is observed and depends on the nature of the substituents connected to C-1 of bromomethyldimethylsilyl propargyl ether derivatives 1. Radical cyclization of 5-bromomethyldimethylsiloxy-2,2,5-trimethyl-3-hexyne 1b is totally stereoselective and a very
    用Bu 3 SnD进行的实验表明,三取代的乙烯基自由基2从氢化中双分子提取氢。观察到高度的立体选择性,并取决于与溴甲基二甲基甲硅烷炔丙基醚生物1的C-1连接的取代基的性质。5-溴甲基二甲基甲硅烷氧基-2,2,5-三甲基-3-己炔1b的自由基环化是完全立体选择性的,并且还观察到非常有趣的(1,4)氢转移。当t-Bu基团被TMS取代时,发现相反的立体选择性显示出相对于空间效应,电子效应的影响更大。
