  日期：2015.6

  Intermolecular oxidative cyclotrimerization reactions of alkenes and aromatic compounds with DDQ and trifluoromethanesulfonic acid are described. Scholl-type oxidation reactions involving alkenes have not previously been demonstrated. Moreover, the DDQ/acid system has never been used for intermolecular oxidative cyclization reactions. This convenient, metal-free reagent system (DDQ/TfOH) is advantageous

  描述了烯烃和芳族化合物与DDQ和三氟甲磺酸的分子间氧化环三聚反应。以前尚未证明涉及烯烃的肖尔型氧化反应。此外，DDQ /酸体系从未用于分子间氧化环化反应。对于金属基Scholl型氧化剂而言，这种方便的无金属试剂系统（DDQ / TfOH）具有优势，因为它消除了作为竞争性副反应的芳香族化合物卤化的可能性。

  Monosubstituted cyanoacetic esters, obtained by condensation of 1-bromo-3(s)-phenoxypropanes (s = o-Cl, o-Br, o-I, o-, m-, and p-NO2) or 1-bromo-2(s)-phenoxyethanes (s = o-Cl, o-Br, o-I, and m-NO2) with ethyl cyanoacetate by means of potassium carbonate, were transformed through a Curtius degradation into cyanoacetisocyanates. These compounds by hydrolysis in acid or alkaline medium gave α-amino acids. However

  单取代的氰基乙酸酯，通过 1-bromo-3(s)-phenoxypropanes (s = o-Cl, o-Br, oI, o-, m-, 和 p-NO2) 或 1-bromo-2(s) 缩合获得)-苯氧基乙烷（s = o-Cl、o-Br、oI 和 m-NO2）与氰乙酸乙酯通过碳酸钾，通过 Curtius 降解转化为氰基乙酰异氰酸酯。这些化合物通过在酸性或碱性介质中水解产生α-氨基酸。然而，相应的羧苄氧基或羧乙氧基氨基腈的水解提供了更好的产率。羧苄氧基氨基腈在盐酸水溶液中比羧甲氧基氨基腈更容易水解。此外，干盐酸对羧苄氧基衍生物的温和作用很容易产生α-氨基酸，而对羧甲氧基衍生物进行类似处理则产生了羧甲氧基氨基酸。
