  摘要：

  在KOH处理下，将烷-4-炔醛与脂肪族二胺在DMSO中进行环化反应，可得到双环N,N-烯胺醛。研究表明，1,3-二氨基丙烷和N-甲基-1,3-二氨基丙烷分别以45—78%的产率生成(E)-6-(芳甲叉基)八氢吡咯并[1,2-a]嘧啶，而1,2-二氨基乙烷则以高达75%的总产率生成5-(芳甲叉基)六氢吡咯并[1,2-a]咪唑的E型和Z型异构体混合物。这些新型串联环化反应的机理包括形成亚胺和环状二胺的平衡混合物，随后发生具有显著离子特性的三键分子内氢胺化反应。

  A series of 7-chloro-2,3-dihydro-2-[1-(pyridinyl)alkyl]-pyridazino[4,5-b]quinoline-1,4,10(5H)-triones were synthesized and found to have potent activity at the glycine site of the NMDA receptor. In some cases, these compounds possessed poor aqueous solubility that may have contributed to poor rat oral bioavailability. Subsequently, compounds have been identified with improved aqueous solubility and oral bioavailability. Several of these compounds were examined in a rat chronic constrictive injury (CCI) model of neuropathic pain and found to have potent activity when dosed orally.

  A cyclization of alk-4-ynals with aliphatic diamines in DMSO upon treatment with KOH was found to lead to bicyclic N,N-enaminals. The studies of this reaction showed that 1,3-diaminopropane and N-methyl-1,3-diaminopropane gave (E)-6-(arylmethylidene)octahydropyrrolo[1,2-a]pyrimidines in 45—78% yields, whereas 1,2-diaminoethane gave 5-(arylmethylidene)hexahydropyrrolo[1,2-a]imidazoles as mixtures of E- and Z-isomers in up to 75% total yield. The mechanism of these new cascade cyclization reactions includes formation of the equilibrium mixtures of imines and cyclic aminals with subsequent intramolecular hydroamination of the triple bond having considerable ionic character.

  Hot couple: Propargyl azides were coupled with carboxylic acids by an iron‐catalyzed dehydrogenative CO bond formation (see scheme). This method enables propargylic CH functionalization under mild reaction conditions and also may involve the application of the azido moiety as an assisting group in CH activation.
