  Selective and Efficient Oxidation of Benzylic Alcohols to Benzaldehydes and Methyl Benzoates by Dibromo-5,5-dimethylhydantoin

  摘要：

  A selective and efficient method of oxidizing benzyl alcohols to benzaldehydes and methyl benzoates by using 1,3-dibromo-5,5-dimethylhydantoin (DBDMH) as oxidant is developed. One-step conversion of benzyl alcohols to methyl benzoates in methanol at room temperature for 12 hours is achieved without any catalysts. Moreover, para-substituted benzyl alcohols are obtained in 86-98% yield. When dichloromethane is used as solvent, further oxidation of benzaldehydes to esters is well controlled, selectively affording benzaldehydes in 89-99% yield within 30 minutes.[Supplementary materials are available for this article.

  A series of arylthioureas (1), aromatic aldehyde thiosemicarbazones (2) and 5-aryl-2-furfuraldehyde thiosemicarbazones (3) were condensed with 2,4-dichloro-5-fluorophenacyl bromide to yield respective arylaminothiazoles, arylidene/5-aryl-2-furfurylidene hydrazinothiazoles (4). The newly synthesized compounds were characterized by IR, 1H-NMR and mass spectral studies. These compounds were also screened

  trimethoprim-resistant bacteria, synthetic methods were needed to prepare a diverse array of 3-aryl-propynes with various substitutions at the propargyl position. A direct route was sought whereby nucleophilic addition of acetylene to aryl carboxaldehydes would be followed by reduction or substitution of the resulting propargyl alcohol.

  Here, we report on the synthesis of libraries of new 5-arylidene-2-thioxo-1,3-thiazolidin-4-ones 3 (twenty-two compounds) and new 2-amino-5-arylidene-1,3-thiazol-4(5H)-ones 5 (twenty-four compounds) with stereo controlled Z-geometry under microwave irradiation. The 46 designed final compounds were tested in order to determine their activity against four representative protein kinases (DYR1A, CK1, CDK5/p25, and GSK3α/β). Among these 1,3-thiazolidin-4-ones, the molecules (5Z) 5-(4-hydroxybenzylidene)-2-thioxo-1,3-thiazolidin-4-one 3e (IC50 0.028 μM) and (5Z)-5-benzo[1,3]dioxol-5-ylmethylene-2-(pyridin-2-yl)amino-1,3-thiazol-4(5H)-one 5s (IC50 0.033 μM) were identified as lead compounds and as new nanomolar DYRK1A inhibitors. Some of these compounds in the two libraries have been also evaluated for their in vitro inhibition of cell proliferation (Huh7 D12, Caco2, MDA-MB 231, HCT 116, PC3, and NCI-H2 tumor cell lines). These results will enable us to use the 1,3-thiazolidin-4-one core as pharmacophores to develop potent treatment for neurological or oncological disorders in which DYRK1A is fully involved.

  在这里，我们报道了在微波辐射下合成了新的5-芳基亚基-2-硫代-1,3-噻唑啉-4-酮3类（二十二个化合物）和新的2-氨基-5-芳基亚基-1,3-噻唑-4（5H）-酮5类（二十四个化合物），具有立体控制的Z-几何构型。设计的46个最终化合物被测试，以确定它们对四种代表性蛋白激酶（DYR1A、CK1、CDK5/p25和GSK3α/β）的活性。在这些1,3-噻唑啉-4-酮中，分子（5Z）5-（4-羟基苯基亚基）-2-硫代-1,3-噻唑啉-4-酮3e（IC50为0.028μM）和（5Z）-5-苯并[1,3]二氧杂环-5-基亚甲基-2-（吡啶-2-基）氨基-1,3-噻唑-4（5H）-酮5s（IC50为0.033μM）被确定为引物化合物和新的纳摩尔级DYRK1A抑制剂。这两个库中的一些化合物也已评估其对细胞增殖的体外抑制作用（Huh7 D12、Caco2、MDA-MB 231、HCT 116、PC3和NCI-H2肿瘤细胞系）。这些结果将使我们能够利用1,3-噻唑啉-4-酮核作为药效团，开发用于治疗DYRK1A完全参与的神经或肿瘤疾病的有效治疗方法。
