  通过简单，可调整的策略组装萜类核

  摘要：

  氧化的多环萜类天然产物具有重要的生物活性。尽管已经广泛研究了这种萜烯的全合成，但是允许氧原子和其他官能团的受控放置的合成策略仍然是一个挑战。本文中，我们提出了一种简单，可扩展且可调的合成策略，可从环烷酮，丙二腈和烯丙基亲电试剂中组装类萜类聚环烷烃，这些试剂种类丰富。

• Synthetic Studies on Wedeligenin: Preparation of 3-Hydroxy-Substituted Decalincarbonitriles as a Model for 'A Ring' Annulation
  作者：JK Macleod、TF Molinski

  DOI：10.1071/ch9901309

  日期：——

  Six new 3-hydroxydecalincarbonitriles were synthesized by employing an annulation strategy involving intramolecular alkylation of 5-bromoalkyl substituted malononitriles or acetonitriles. 2-Allyl-2-methylcyclohexanone was condensed with malononitrile to give the dialkylcyclohexylidenepropanedinitrile (14). Alternatively, Horner-Emmons- Wittig condensation of the same ketone with diethyl cyanomethylphosphonate gave the corresponding acetonitrile (28). Reduction of the dinitrile with sodium borohydride to give a mixture of cis and trans cyclohexyl malononitriles followed by epoxidation of the allyl substituent, gave a separable mixture of four epoxides, two of which, (17) and (19), were site-selectively ring-opened to the bromohydrins. Each bromohydrin was quantitatively converted into its respective O- trimethylsilyl bromohydrin ether and cyclized to afford the respective decalindicarbonitriles (6) and (7). The substituted acetonitrile (28) was reduced to a 5 : 2 mixture of the corresponding cyclohexylacetonitriles with magnesium in methanol and the products were carried through to their respective O- trimethylsilyl bromohydrin ethers and cyclized to afford decalincarbonitriles (8)-(11). The structure and stereochemistry of the new decalins were assigned by 1H and 13C n.m.r. spectroscopy.

  通过对 5-溴烷基取代的丙二腈或丙酮腈进行分子内烷基化的环化策略，合成了六种新的 3-羟基癸烷碳腈。将 2-烯丙基-2-甲基环己酮与丙二腈缩合，得到二烷基环己亚基丙二腈（14）。另外，同样的酮与氰甲基膦酸二乙酯进行 Horner-Emmons- Wittig 缩合，得到相应的乙腈（28）。用硼氢化钠还原二腈，得到顺式和反式环己基丙二腈的混合物，然后进行烯丙基取代基的环氧化反应，得到四种环氧化物的可分离混合物，其中两种，即 (17) 和 (19)，可通过位点选择性开环生成溴水林。每个溴氢林都定量转化为各自的 O-三甲基硅溴氢林醚，并环化生成各自的癸醛二腈（6）和（7）。将取代的乙腈 (28) 在甲醇中用镁还原成 5 : 2 的相应环己基丙酮腈混合物，然后将产物转移到各自的 O-三甲基硅基溴化氢醚中并环化，得到癸醛碳腈 (8)-(11)。通过 1H 和 13C n.m.r.光谱测定了这些新癸醛的结构和立体化学性质。

  Oxygenated, polycyclic terpenoid natural products have important biological activities. Although total synthesis of such terpenes is widely studied, synthetic strategies that allow for controlled placement of oxygen atoms and other functionality remains a challenge. Herein, we present a simple, scalable, and tunable synthetic strategy to assemble terpenoid‐like polycycloalkanes from cycloalkanones
