  Microwave-Assisted Fluorination of 2-Acylpyrroles: Synthesis of Fluorohymenidin

  摘要：

  Treatment of mono- and nonbrominated 2-acylpyrroles with Selectfluor under microwave conditions leads to fluorination of the pyrrole ring in the 5-position. In particular, 2-trichloroacetylated pyrrole can be fluorinated. As an example, dihydrofluorohymenidin was synthesized and dehydrogenated to fluorohymenidin as the first fluorinated pyrrole-imidazole alkaloid. Introduction of the vinyl double bond was achieved by chlorination of the 2-aminoimidazole moiety, followed by dehydrochlorination at 100 degrees C in DMF.

  日期：2010.5.21

  A novel, one-step method for the synthesis of tri- and tetrasubstituted pyrimidin-4-ones is reported. This method involves a titanium(IV)-mediated cyclization involving two sequential condensations of primary and β-ketoamides. The reaction is operationally facile, readily scalable, and offers rapid entry into differentially substituted pyrimidin-4-one scaffolds. The high functional group compatibility

  The selective synthesis of aromatic and heteroaromatic amides through base-catalysed hydration of nitriles was achieved using inexpensive and commercially available NaOH as the only catalyst. A wide range of nitriles was selectively converted to their corresponding amides. Kinetic studies show that the double hydration of nitriles towards undesirable carboxylic acids is negligible under our reaction

  使用廉价和可商购的NaOH作为唯一催化剂，可以通过碱催化腈的水合反应选择性合成芳族和杂芳族酰胺。各种各样的腈被选择性地转化为其相应的酰胺。动力学研究表明，在我们的反应条件下，腈类向不想要的羧酸的双重水合作用可以忽略不计。
