    Various 3-arylisocoumarins (5, 6, 8, 10, 11, and 12) were simply prepared in high yields by heating homophthalic acids (1-4) with aromatic acyl chlorides. 8-Hydroxy-3-phenylisocoumarin (17) and 8-acetoxy-3-phenylisocoumarin (18), and 8-hydroxy-3-(p-methoxyphenyl) isocoumarin (19) were obtained by alkaline hydrolysis of 10 and 11, respectively, followed by treatment with acetic anhydride. 3, 4-Dihydro-8-hydroxy-3-phenyl-isocoumarin (24) was prepared from 10 by alkaline hydrolysis followed by reduction with sodium borohydride then heating with acetic anhydride. 3-(p-Hydroxyphenyl)-isocoumarin (7), 8-hydroxy-3-(p-hydroxyphenyl) isocoumarin (9), 5-chloro-8-hydroxy-6-methoxy-3-phenylisocoumarin (13), and 3, 4-dihydro-3-(p-hydroxyphenyl) isocoumarin (23) were prepared by demethylation of 6, 8, 12 and 22, respectively. All the prepared isocoumarins and some other isocoumarin derivatives (25-30) were examined in vitro for antifungal activity. The structure-activity relationships are discussed.
    通过加热均苯二甲酸(1-4)和芳香酰基,可以简单地高产率制备出各种 3-芳基异香豆素(5、6、8、10、11 和 12)。8- 羟基-3-苯基异香豆素(17)和 8-乙酰氧基-3-苯基异香豆素(18)以及 8-羟基-3-(对甲氧基苯基)异香豆素(19)分别是通过碱解 10 和 11,然后用乙酸酐处理而得到的。3,4-二氢-8-羟基-3-苯基异香豆素(24)是由 10 通过碱性解,然后用硼氢化钠还原,再用乙酸酐加热制备的。3-(对羟基苯基)-异香豆素(7)、8-羟基-3-(对羟基苯基)异香豆素(9)、5--8-羟基-6-甲氧基-3-苯基异香豆素(13)和 3,4-二氢-3-(对羟基苯基)异香豆素(23)分别由 6、8、12 和 22 脱甲基制备而成。对所有制备的异香豆素及其他一些异香豆素生物(25-30)进行了体外抗真菌活性检测。本文对其结构-活性关系进行了讨论。
  • Development of Bioactive Functions in Hydrangeae Dulcis Folium. VI. Syntheses of Thunberginols A and F and Their 3'-Deoxy-Derivatives Using Regiospecific Lactonization of Stilbene Carboxylic Acid: Structures and Inhibitory Activity on Histamine Release of Hydramacrophyllols A and B.

    Lactonization reaction of 2-carboxystilbene mediated by copper(II) chloride proceeded regiospecifically to give the five-membered lactone, while the bromolactonizations using N-bromosuccinimide and anodic oxidation were found to furnish the six-membered lactone. Using these regiospecific lactonization reactions as a key step, antiallergic and antimicrobial isocoumarins and the benzylidenephthalides thunberginols A and F and their 3'-deoxyanalogs were synthesized from phyllodulcin and hydrangenol.Two phthalides called hydramacrophyllols A and B were isolated from Hydrangeae Dulcis Folium and their stereostructures were determined on the basis of physicochemical and chemical evidence, which included the syntheses of hydramacrophyllols A and B from hydrangenol by the application of the lactonization method using copper(II)chloride. In addition, hydramacrophyllols A and B were found to exhibit an inhibitory effect on the histamine release from rat peritoneal exudate cells induced by antigen-antibody reaction.
    (II)介导的 2-羧基二苯乙烯的内酯化反应进行了区域特异性反应,生成了五元内酯,而使用 N-代琥珀酰亚胺和阳极氧化进行的内酯化反应则生成了六元内酯。利用这些区域特异性内酯化反应作为关键步骤,从phyllodulcin 和 hydrangenol 合成了抗过敏和抗菌的异香豆素和苯亚甲基thunberginols A 和 F 及其 3'-deoxyanalogs 。根据物理化学化学证据,从绣线菊叶中分离出了两种名为飞蓟醇 A 和 B 的邻苯二甲酸盐,并确定了它们的立体结构,其中包括应用(II)内酯化法从飞蓟醇合成了飞蓟醇 A 和 B。此外,还发现合麦考 A 和 B 对抗原-抗体反应诱导的大鼠腹腔渗出细胞释放组胺具有抑制作用。
