  摘要：

  An efficient method for the synthesis of mono- and disubstituted 2-amino-1H-imidazoles via microwave-assisted hydrazinolysis of substituted imidazo[1,2-a]pyrimidines is reported. This protocol avoids strong acidic conditions and is superior to the classical cyclocondensation of alpha-haloketones with N-acetylguanidine. (C) 2009 Elsevier Ltd. All rights reserved.

• Synthesis and Antibacterial Activity of Some Imidazo(1,2-a)pyrimidine Derivatives.
  作者：Yveline RIVAL、Gerard GRASSY、Georges MICHEL

  DOI：10.1248/cpb.40.1170

  日期：——

  A series of 75 imidazo[1,2-a]pyrimidine derivatives were synthesized. The "in vitro" antibacterial activity of these compounds and their corresponding alpha-bromoketones against a variety of gram (+), gram (-) bacteria and Mycobacterium species is reported. Some of the prepared derivatives exhibited potent antimicrobial activity.

  合成了75种咪唑并[1,2-a]嘧啶衍生物。据报道，这些化合物及其相应的α-溴代酮对多种革兰氏（+），革兰氏（-）细菌和分枝杆菌属物种具有“体外”抗菌活性。一些制备的衍生物表现出有效的抗微生物活性。

  A simple and highly efficient metal-free method has been developed for hydroxyfluoroalkylation of indoles and imidazo[1,2-a]pyridines via TEMPO-mediated C(sp3)–H and C(sp2)–H bond cross-dehydrogenative coupling of fluorinated alcohols and indoles. The protocol showed broad substrate scope, afforded good yields of hydroxyfluoroalkylated products, and was amenable for scale-up. Mechanistic investigation

  Substituted 2-naphthoic acids of structural formula I are effective as antagonists of the biological activity of GPR105 protein. They are useful for the treatment, control or prevention of disorders responsive to antagonism of this receptor, such as diabetes, particularly, Type 2 diabetes, insulin resistance, hyperglycemia, lipid disorders, obesity, atherosclerosis, and conditions associated with the Metabolic Syndrome.

  结构式I中的2-萘甲酸替代物对GPR105蛋白的生物活性具有拮抗作用。它们可用于治疗、控制或预防对该受体拮抗有响应的疾病，如糖尿病，特别是2型糖尿病，胰岛素抵抗，高血糖，脂质紊乱，肥胖，动脉粥样硬化以及与代谢综合征相关的疾病。

  PEG‐400[poly(ethylene glycol‐400)] is used as a “green” recyclable solvent in the one‐pot synthesis of 2‐arylimidazo[1,2‐a]pyrimidines by reaction with ketones, [hydroxyl(2,4‐dinitrobenzenesulfonyloxy)‐iodo]benzene (HDNIB), and 2‐aminopyrimidine. Significant rate enhancements and improved yields have been observed.
