  摘要：

  已经开发了使用N，N-二溴-对甲苯磺酰胺（TsNBr 2）的α，β-不饱和羧酸的脱羧溴化的快速方法。在乙腈中碳酸钾存在下，用TsNBr 2处理肉桂酸可生成相应的β-溴苯乙烯。（E的排他性在很短的时间内（5-15分钟）以立体选择性的方式观察到了）-β-溴苯乙烯。该方法进一步扩展为从相应的丙酸获得1-溴代炔烃。当在室温下在乙腈中以DBU为碱存在下进行反应时，观察到溴炔的瞬时形成。在温和的反应条件下，可以将各种各样的肉桂酸和丙酸分别转化为相应的β-溴代苯乙烯和1-溴代炔烃，且产率高至优异。

  Synthesis and structure–activity relationships of phenyl-substituted coumarins with anti-tubercular activity that target FadD32

  摘要：

  In an effort to develop new and potent agents for therapy against tuberculosis, a high-throughput screen was performed against Mycobacterium tuberculosis strain H37Rv. Two 6-aryl-5,7-dimethyl-4-phenylcoumarin compounds 1a and 1b were found with modest activity. A series of coumarin derivatives were synthesized to improve potency and to investigate the structure-activity relationship of the series. Among them, compounds 1o and 2d showed improved activity with IC90 of 2 mu M and 0.5 mu M, respectively. Further optimization provided compound 3b with better physiochemical properties with IC90 0.4 mu M which had activity in a mouse model of infection. The role of the conformation of the 4- and 6-aryl substituents is also described. (c) 2013 Elsevier Ltd. All rights reserved.

  A novel chloropalladation-initiated intermolecular oxyvinylcyclization of alkenes with alkynoic acids or alkynols is developed. This protocol provides a series of 3-methylene γ-lactone and tetrahydrofuran derivatives in moderate to excellent yields with high stereoselectivities in the presence of PdCl2 and CuCl2 or CuCl2·2H2O. Besides a broad substrate scope, this method has the advantages of mild

  situ activation of 3-arylpropiolic acids with T3P® (n-propylphosphonic acid anhydride) initiates a domino reaction furnishing 4-arylnaphtho[2,3-c]furan-1,3-diones in excellent yields. Upon employing these anhydrides as reactive intermediates blue-luminescent 4-aryl-1H-benzo[f]isoindole-1,3(2H)-diones are formed by consecutive pseudo three-component syntheses in a one-pot fashion. The Stokes shifts correlate

  Ynones are privileged building blocks in various organic syntheses of heterocyclic derivatives due to their multifunctional nature, and flavones are an important class of natural products with a wide range of biological activities. We describe the catalytic double decarboxylative alkynylation of arylpropiolic acids with α‐keto acids. With Ag(I)/persulfate as the catalysis system, the valuable ynones
