    Synthesis and in vitro inhibitory activity on human platelet aggregation of novel properly substituted 4-(1-piperazinyl)coumarins
    摘要:
    Pursuing our chemical and biological studies in this field, we described the multistep preparation of the new 5-, 6-, or 7-alkoxy and 7-alkoxy-8-methyl substituted 4-(1-piperazinyl)coumarins 5d-v, as well as the in vitro evaluation of their inhibitory activity on human platelet aggregation induced in platelet-rich plasma by ADP, collagen or the Ca2+ ionophore A23187. Compounds 5h-j,p,r-u showed notably high activity towards all the platelet aggregation inducers used, and the most active one, 8-methyl-4-(1-piperazinyl)-7-(3-pyridylmethoxy)coumarin (5t), proved to be a potent in vitro antiplatelet agent.

    摘要:
    已经开发了一种通过 C-H 活化从 3-iodo-4-aryloxy 香豆素的分子内环化合成各种香豆素的有效方案。当在乙酸钠存在下用 10% Pd/C (0.3 mol% Pd) 处理 3-iodo-4-aryloxy 香豆素时,相应的香豆素以良好的产率产生。在多达三个连续循环中研究了钯催化剂的可重复使用性,发现反应的产率几乎没有改变。顺序碘化和O4-羟基香豆素的α-芳基化产生3-碘-4-芳氧基香豆素也可以在一锅两步法中以高产率从芳基碘化物开始。发现新戊酸是后一种方法生产 3-碘-4-苯氧基香豆素的最有效添加剂。带有给电子基团和吸电子基团的不同官能团也对反应条件具有耐受性。

    An efficient protocol for synthesizing furo[3,2-c]coumarin derivatives is described. The novel reaction could afford the desired furocoumarins with good to excellent yields in a mild and rapid manner. Large substrate scope screening and scale-up preparation have also been accomplished, and selected compounds were evaluated for their photophysical properties.

    A novel and rapid assembly of an interesting class of furocoumarins-4H-furo[3,2-c]chromen-4-ones has been successfully achieved using one-pot sequential coupling/cyclization strategy with easily available starting materials 3-bromo-4-acetoxycoumarins and terminal alkynes. The key synthesis involves Pd/Cu-catalyzed alkynylation with in situ prepared dialkynylzincs followed by intramolecular hydroalkoxylation.
