  Synthesis and evaluation of some novel isochroman carboxylic acid derivatives as potential anti-diabetic agents

  摘要：

  A series of novel isochroman mono-carboxylic acid derivatives were synthesized, characterized and evaluated for their ability to inhibit protein tyrosine phosphatase 1B (PTP1B) in vitro in order to use them as potential anti-diabetic agents. Analysis of structure-activity relationships led to the identification of potent compound 4n which inhibited PTP1B with IC50 value of 51.63 +/- 0.91 nM. In general, high potency was associated with a dithiolane ring with a spacer of five carbons to the isochroman ring. Compound 4n has been selected for in vivo evaluation as drug candidate for anti-diabetic activity. (C) 2009 Elsevier Masson SAS. All rights reserved.

  2-Azaadamantane N-氧基（AZADO）/ Cu催化可实现含电子丰富的二价硫官能团的醇的化学选择性好氧氧化

  摘要：

  在现代有机化学中，有时将含有富电子功能的硫官能团（例如1,3-二硫醚和硫化物）的醇化学选择性氧化成其相应的具有硫基的羰基化合物，这可能是一项艰巨的任务。报道了这种转化的可靠方法，其特征在于使用环境空气作为末端氧化剂的氮杂金刚烷型硝基氧基自由基/铜催化。通过与各种常规醇氧化方法进行比较，证明了所开发方法的优越性。

  The chemoselective oxidation of alcohols containing electron-rich sulfur functionalities (e.g., 1,3-dithianes and sulfides) into their corresponding carbonyl compounds with the sulfur groups can sometimes be a demanding task in modern organic chemistry. A reliable method for this transformation, which features azaadamantane-type nitroxyl radical/copper catalysis using ambient air as the terminal oxidant
