    摘要:
    4-Hydroxymethyl-2,4-pentadienoate was effectively synthesized and used for a synthetic entry to keto bridged bicyclo [n.3.1] alkanones and for the synthesis of a 12-membered macrodilide characterized by two trans double bonds, part of two vinylogous alpha-methylene lactone units.

  • Photochemical Ring Opening of Tricyclic Hemiketals: Diastereoselective Construction of Functionalized Medium-Sized Carbocycles and a Diquinane
    作者:Alfred Hassner、Namakkal G. Ramesh
    DOI:10.1055/s-2004-820044
    日期:——
    stereoselective construction of functionalized medium-sized carbocycles and a diquinane from bicyclo[3.n.1]alkanones is reported. The key step is the hypervalent iodine mediated photochemical ring opening of tricyclic hemiketals, formed by dihydroxylation of methylene-bicyclo[3.3.1]nonan-9-one and methylene-bicyclo[3.2.1]octan-8-one, to afford eight- and seven-membered carbocyclic rings, respectively
    报道了一种从双环 [3.n.1] 烷酮轻松构建功能化中等大小碳环和二喹烷的立体选择性结构。关键步骤是高价介导的三环缩酮化学开环,由亚甲基-双环[3.3.1]壬烷-9-酮和亚甲基-双环[3.2.1]辛烷-8-酮二羟基化形成,得到八- 和七元碳环,分别。随后使用 LDA 实现了环辛烷向二喹烷的转化。该反应还扩展到稠合双环系统的合成。
  • Studies Towards the Synthesis of Functionalized Medium-Sized Carbocyclic and Fused Bicyclic Systems by Alkoxy Radical Fragmentation (ARF)
    作者:Namakkal G. Ramesh、Alfred Hassner
    DOI:10.1002/ejoc.200400763
    日期:2005.5
    The stereoselective construction of polyfunctionalized medium-sized carbocyclic and fused bicyclic systems from substituted bicyclo[3.n.1]alkanones has been studied; the strategy employed involved Suarez’s alkoxy radical fragmentation reaction (ARF) as the key step. The scope of the reaction was examined and this methodology was found to be especially useful for stereo- and regioselective construction
    研究了由取代的双环[3.n.1]烷酮立体选择性构建多官能化中型碳环和稠合双环系统;所采用的策略涉及苏亚雷斯的烷氧基自由基裂解反应 (ARF) 作为关键步骤。对反应范围进行了检查,发现该方法特别适用于八元碳环的立体和区域选择性构建,包括双环 [6.4.0] 十二烷系统,这是一种存在于各种生物活性天然产物中的框架. 该反应也成功地用于合成七元碳环,但选择性较低。发现分子中半缩酮官能团的存在对于 ARF 反应的发生是必不可少的;因此无法获得九元和十元环类似物,因为前体双环酮不会形成所需的半缩酮。MM 计算证实了这一点。最后,还合成了二喹烷。(© Wiley-VCH Verlag GmbH & Co.
