Certain disubstituted 3,8-diaza-bicyclo[4.2.0]octane and 3,6-diazabicyclo [3.2.0]heptane are described, which are useful as orexin inhibitors. Such compounds may be useful in pharmaceutical compositions and methods for the treatment of diseased states, disorders, and conditions mediated by orexin activity, such as insomnia.

An efficient strategy toward 4-arylquinolines and 4-arylpyrimidines from readily available precursors is described. Oxidative annulationpromoted by K2S2O8 involving anilines, aryl ketones, and DMSO as a methine (═CH−) equivalent leads to 4-arylquinolines via a cascade that entails generation of a sulfenium ion, subsequent C–N and C–C bond formations, and cyclization. The application of this strategy
描述了从容易获得的前体制备4-芳基喹啉和4-芳基嘧啶的有效策略。K 2 S 2 O 8促进的涉及苯胺,芳基酮和DMSO的亚甲基(═CH-)等效的氧化环化反应通过级联反应生成4-芳基喹啉,该级联反应会生成generation离子,随后的C–N和C– C键的形成和环化。还描述了该策略在乙酰苯甲酰胺甲酰胺偶联物的活化中对4-芳基嘧啶合成的应用。

A facile and practical approach for the preparation of substituted pyrimidines from ketones, NH4OAc, and N,N-dimethylformamide dimethyl acetal has been described. This NH4I-promoted three-component tandem reaction affords a broad range of substituted pyrimidines in acceptable yields under metal- and solvent-free conditions. The present methodology features the advantages of simple and easily available
已经描述了由酮、NH 4 OAc和N , N-二甲基甲酰胺二甲基缩醛制备取代嘧啶的简单且实用的方法。这种 NH 4 I 促进的三组分串联反应在无金属和无溶剂的条件下以可接受的产率提供了多种取代的嘧啶。该方法具有起始原料简单易得、无金属和溶剂条件、底物范围广、官能团耐受性好以及克级合成等优点。
