  高度紧张的二氢蒽醌：氧化与消除

  摘要：

  为了开发高度紧张的蒽醌的合成，研究了紧张的二氢蒽醌的化学性质。发现（1,4-二氢-9,10-二氧代蒽-1-基）乙酸盐与三乙胺在好氧条件下的反应取决于乙酸盐上的取代度。带有二甲基乙酸酯的二氢蒽醌仅进行烯醇消除，而没有乙酸酯取代的二氢蒽醌则按预期方式脱氢。此外，由于竞争性的碘内酯化反应，使用碘氧化环己二烯环失败。通过用酸性乙醇处理所得内酯，可以低产率制备所需的应变蒽醌。

  The present invention relate to a novel silane coupling agent and a medical and/or dental curable composition comprising the same. It is an object of the present invention to provide a novel silane coupling agent that imparts high affinity to a radical polymerizable monomer, thereby imparting high mechanical strength, flexibility and durability when used for a medical and/or dental curable composition, and an inorganic filler surface-treated with the novel silane coupling agent and a novel medical and/or dental curable composition. A silane coupling agent including repeating units such as a urethane bond and polyethylene glycol (ether bond) at a specific position is used.

  Reaction of 1,2-diaminioethane (ethylenediamine) with electron-deficient alkynes leads to full scission of the C≡C bond even in the absence of a keto group directly attached to the alkyne. This process involves oxidation of one of the alkyne carbons into C2 of a 2-R-4,5-dihydroimidazole with the concomitant reduction of the other carbon to a methyl group. The sequence of Sonogashira coupling with the

  1,2-二氨基乙烷（乙二胺）与缺电子的炔烃反应会导致C≡C键完全断裂，即使没有直接连接到炔烃上的酮基也是如此。该方法涉及将炔烃碳之一氧化成2 - R -4,5-二氢咪唑的C2，同时将另一个碳还原成甲基。这项工作中所述的Sonogashira与乙二胺介导的片段化偶联的序列可用于甲基或4,5-二氢咪唑-2-基部分选择性取代芳基卤化物中的卤素。
