  Efficient and Benign One-Pot Conversion of N-Tosyl-1,4,5,6-tetrahydropyrimidines to Pyrimidines via Tandem β-Elimination and Aromatization

  摘要：

  An efficient, mild, benign, and practical method for one-pot conversion of N-tosyl-1,4,5,6-tetrahydropyrimidines into pyrimidines is discussed in detail. In this method, N-tosyl-1,4,5,6-tetrahydropyrimidines are first prepared via N-tosylation of tetrahydropyrimidines with TsCl and then treated with 1.5 equivalents of NaOH in dimethylsulfoxide (DMSO) under air at 60 degrees C to afford corresponding pyrimidines in 70-95% yields via cascade -elimination and aromatization.

  Moreover, the CO and CO2 generated could be further utilized directly. Thus, chlorine-containing hydrocarbon waste, including mixed waste, can serve as chlorination reagents that neither generate hazardous by-products nor involve specialty chlorination reagents. This tandem catalytic approach represents a promising method for the viable management of a wide and diverse range of chlorine-containing hydrocarbon

  氯化化合物无处不在。然而，由于垃圾填埋和焚烧等常规处理方法不适用，含氯废物的积累会对人类健康和环境产生负面影响。在这里，我们报告了一种基于铜和钯催化剂以及 NaNO 3促进剂的可持续方法，用于对含氯碳氢化合物废物进行增值，包括固体（氯化聚合物）和液体（氯化溶剂）。在此过程中，废物在 N 导向芳烃存在下被氧化释放出氯，从而获得有价值的芳基氯化物，例如 FDA 批准的药物 vismodegib。剩余的烃组分被矿化以提供CO、CO 2和H 2 O。此外，产生的CO和CO 2可以进一步直接利用。因此，含氯烃废物，包括混合废物，可以用作氯化试剂，既不会产生危险的副产物，也不涉及特种氯化试剂。这种串联催化方法代表了一种有前途的方法，可以有效管理各种含氯烃废物。

• Synthesis and structure-function analysis of Fe(II)-form-selective antibacterial inhibitors of Escherichia coli methionine aminopeptidase

  Methionine aminopeptidase (MetAP) is a promising target for the development of novel antibacterial, antifungal and anticancer therapy. Based on our previous results, catechol derivatives coupled with a thiazole or thiophene moiety showed high potency and selectivity toward the Fe(II)-form of Escherichia coli MetAP, and some of them clearly showed antibacterial activity, indicating that Fe(II) is likely the physiologically relevant metal for MetAP in E. coli and other bacterial cells. To further understand the structure-function relationship of these Fe(II)-form selective MetAP inhibitors, a series of catechol derivatives was designed and synthesized by replacement of the thiazole or thiophene moiety with different five-membered and six-membered heterocycles. Inhibitory activities of these newly synthesized MetAP inhibitors indicate that many five- and six-membered rings can be accommodated by MetAP and potency on the Fe(II)-form can be improved by introducing substitutions on the heterocyles to explore additional interactions with the enzyme. The furan-containing catechols 11-13 showed the highest potency at 1 mu M on the Fe(II)-form MetAP, and they were also among the best inhibitors for growth inhibition against E. coli AS19 strain. These findings provide useful information for the design and discovery of more effective MetAP inhibitors for therapeutic applications. (C) 2009 Elsevier Ltd. All rights reserved.
