  An efficient route for commercially viable syntheses of furan- and thiophene-anellated β-hydroxychalcones

  摘要：

  An efficient route for the syntheses of beta-hydroxychalcones containing benzofuran and benzothiophene rings is described. Isoxazolines obtained from oxime-olefin cycloadditions were reduced under pressure to a mixture of products. Isoxazoles obtained from Claisen aroylation of an ester and subsequent acid cyclization, or from isoxazolines via DDQ-mediated dehydrogenation, were subjected to catalytic hydrogenation followed by hydrolysis to afford 1-phenyl-3-(benzofuran-5-yl)-1,3-diketone and 1-phenyl-3(benzothiophene-5-yl)-1,3-diketones in very good yields.

  紫生病菌中新型苯并呋喃化合物的分离，合成及抑制组胺H 1受体基因表达的几种相关衍生物的合成

  摘要：

  从孟加拉国收集的一种植物Tephrosia purpurea中分离出了一种具有苯并呋喃骨架的新型天然化合物。该化合物的化学合成证实了其结构，初步的生物学结果表明其对组胺H 1基因表达具有抑制活性。还合成了一种异构体和四种衍生物，并研究了它们的抑制活性。尽管只能从其天然来源中分离出少量这种化合物，但新开发的方法证明了10 g规模的合成。
