  使用甲酸盐作为还原剂和二氧化碳源的光催化脱氟羧基化

  摘要：

  在此，我们报道了使用甲酸盐作为还原剂和二氧化碳源的苄基 C(sp 3 )–F 键的光催化脱氟羧基化。各种带有伯或仲 C(sp 3 )–F 键的氟化苄可以与 HCOOK 顺利进行脱氟羧化。这种不含过渡金属的策略为获取一系列有价值的芳基乙酸（例如氟比洛芬）提供了一种温和、高效且可持续的方法。该方案还具有催化剂负载量低、反应条件温和、官能团耐受性良好以及良好的可扩展性和可持续性等特点。机理研究表明二氧化碳自由基阴离子 (CO 2 ˙ − ) 是通过氢原子转移（HAT）并作为强还原剂促进氟化苄的单电子还原。随后碳负离子对 CO 2的亲核攻击（两者都是原位生成的中间体）产生了所需的产物，证明了 CO 2捕获过程的高效率。

  Structure-based optimization of oxadiazole-based GSK-3 inhibitors

  摘要：

  Inhibition of glycogen synthase kinase-3 (GSK-3) induces neuroprotective effects, e.g. decreases beta-amyloid production and reduces tau hyperphosphorylation, which are both associated with Alzheimer's disease (AD). The two isoforms of GSK-3 in mammalians are GSK-3 alpha and beta, which share 98% homology in their catalytic domains. We investigated GSK-3 inhibitors based on 2 different scaffolds in order to elucidate the demands of the ATP-binding pocket [1]. Particularly, the oxadiazole scaffold provided potent and selective GSK-3 inhibitors. For example, the most potent inhibitor of the present series, the acetamide 26d, is characterized by an IC50 of 2 nM for GSK-3 alpha and 17 nM for GSK-3 beta. In addition, the benzodioxane 8g showed up to 27-fold selectivity for GSK-3 alpha over GSK-3 beta, with an IC50 of 35 nM for GSK-3 alpha. Two GSK-3 inhibitors were further profiled for efficacy and toxicity in the wild-type (wt) zebrafish embryo assay to evaluate simultaneously permeability and safety. (C) 2012 Elsevier Masson SAS.

• Fluorinated Benzyloxyphenyl Piperidine-4-carboxamides with Dual Function against Thrombosis: Inhibitors of Factor Xa and Platelet Aggregation

  A series of benzyloxy anilides of nipecotic (5, 6) and isonipecotic (7, 8) acids were synthesized and assayed in vitro as inhibitors of ADP-induced platelet aggregation and the blood coagulation enzymes factor Xa (FXa) and thrombin (FIIa). An exploration of effects of the amidine group attached at the piperidine nitrogen,position and substitution (F, phenyl) of the benzyloxy group, and addition of fluorine/s on the second (distal) phenyl ring, led us to single out some promising isonipecotamide derivatives 7. Addition of meta-F and para-CF3 on the distal phenyl ring resulted in a 6-to-18-fold enhancement of the FXa potency and in 2-to-4-fold increase of the antiplatelet potency, the last depending to a large extent upon lipophilicity. Two congeners of N-[3-(1,1'-biphenyl-4-yl)methoxy]phenyl}piperidine-4-carboxamide (7m and 7p) proved to be potent FXa-selective inhibitors (K-i = 130 and 57 nM, respectively) and antiplatelet agents and were identified as leads for developing new dual function antithrombotic drugs.

  Herein, we report a photocatalytic defluorocarboxylation of benzylic C(sp3)–F bonds using formate salts as both a reductant and a carbon dioxide source. A variety of benzyl fluorides, bearing primary or secondary C(sp3)–F bonds, undergo defluorinative carboxylation smoothly with HCOOK. This transition metal-free strategy provides a mild, efficient, and sustainable approach for accessing a series of
