  通过伯烷氧基自由基的 β-断裂从 β-氨基醇合成生物碱类似物

  摘要：

  伯烷氧基的裂解通常是夺氢和其他竞争反应的次要过程。然而，当使用 β-氨基醇作为底物时，断裂以良好到极好的产率进行，并且没有观察到副反应。断裂可以与烯丙基化或烷基化反应相结合，以得到生物碱类似物和官能化的氮杂环。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

• Reactions of 1,2-dehydropyrrolidin-5-one with 1,3-dienes. Synthesis of <i>dl</i>-gephyrotoxin 223AB
  作者：Oliver E. Edwards、Austin M. Greaves、Wing-Wah Sy

  DOI：10.1139/v88-191

  日期：1988.5.1

  Evidence is presented that the regiospecific and often stereospecific pseudo-Diels–Alder reactions of 1,3-dienes with N-acyl immonium salts, derived from 5-ethoxy-2-pyrrolidinone, are stepwise reactions. 6,7-Dehydroindolizidinones, unsaturated lactam esters, and new indene and furan derivatives are described. A synthesis of dl-gephyrotoxin 223AB (indolizidine 223AB) from trans-1,3-heptadiene was achieved

  有证据表明，1,3-二烯与衍生自 5-乙氧基-2-吡咯烷酮的 N-酰基亚铵盐的区域特异性和通常立体特异性的假狄尔斯-阿尔德反应是逐步反应。描述了 6,7-脱氢 indolizidinones、不饱和内酰胺酯和新的茚和呋喃衍生物。实现了从反式-1,3-庚二烯合成 dl-gephyrotoxin 223AB（吲哚里西啶 223AB）。

  efficient synthesis of fused nitrogen heterocycles containing various combinations of five- and eight-membered rings has been developed. This method features the ring-closing metathesis (RCM), which is catalyzed by the molybdenum alkylidene complex 6, of α,ω-dienes that have a nitrogen atom in the chain linking the two olefinic functional groups.

  已经开发出有效合成包含五元和八元环的各种组合的稠合氮杂环的新技术。该方法的特征在于由α，ω-二烯的钼亚烷基络合物6催化的闭环复分解（RCM），该α，ω-二烯在连接两个烯烃官能团的链中具有氮原子。
• Synthesis of alkaloids from aminol derivatives by β-fragmentation of primary alkoxyl radicals
  作者：Alicia Boto、Rosendo Hernández、Adriana Montoya、Ernesto Suárez

  日期：2004.2

  The fragmentation of primary alkoxyl radicals, often described as low yielding and plagued by side reactions, proceeded in good to excellent yields when aminol derivatives were used as substrates. Remarkably, no side reactions such as hydrogen abstraction or oxidation were observed. The fragmentation can be coupled with an alkylation reaction to give 2-substituted pyrrolidine and piperidine rings such

  当将氨基衍生物用作底物时，通常被描述为低产率并受副反应困扰的伯烷氧基自由基的裂解以良好至优异的产率进行。值得注意的是，未观察到副反应，例如氢提取或氧化。该断裂可以与烷基化反应偶联，得到2-取代的吡咯烷和哌啶环，例如生物碱类似物和官能化的手性氮杂环。

• Synthesis of Alkaloid Analogues from β-Amino Alcohols by β-Fragmentation of Primary Alkoxyl Radicals

  fragmentation of primary alkoxyl radicals is usually a minor process with respect to hydrogen abstraction and other competing reactions. However, when β-amino alcohols were used as substrates, the scission proceeded in good to excellent yields and no side reactions were observed. The fragmentation can be coupled with an allylation or alkylation reaction, to give alkaloid analogues and functionalized
