  • Coumarins from the Fruits of <i>Seseli </i><i>d</i><i>evenyense</i>

    Eight new coumarins were isolated from the fruits of Seseli devenyense Simonkai. Their structures were established from NMR and mass data and their absolute configurations from chemical degradation correlation reactions. The new structures are the decanoic and dodecanoic esters of (+)-lomatin (3, 4), the decanoates of (+)-cis-khellactone at positions 4' (5) and 3' (6) as well as the 2'S epimer of 8-(2
    从芝麻雪茄西蒙凯(Seseli devenyense Simonkai)的果实中分离出八种新的香豆素。它们的结构由NMR和质量数据确定,其绝对构型由化学降解相关反应确定。新结构是(+)-lomatin(3,4)的癸酸酯和十二酸酯,在位置4'(5)和3'(6)的(+)-顺式-甲壳酮的癸酸酯以及2'S差向异构体名为devenyol的8-(2,3-二羟基-3-甲基丁基)-7-羟基chromen-2-one(7),其在3'和7位的两个O-单葡糖苷分别称为devenyosides A(8)和B(9) ,以及名为devenyoside C(10)的相应3'-和7-O-二葡萄糖苷。鉴于is科的其他成员仅产生化合物7-9的2'R差向异构体,因此该植物是基于生物多样性的立体化学多样性的一个有趣实例。

  • Phytotoxic Compounds from <i>Prionosciadium </i><i>w</i><i>atsoni</i>
    作者:Norma Valencia-Islas、Hamed Abbas、Robert Bye、Rubén Toscano、Rachel Mata

    日期:2002.6.1
    Bioassay-guided fractionation of a phytotoxic extract of Prionosciadium watsoni led to the isolation of three new pyranocoumarins and two pyranochromones. The new compounds were characterized as propionic acid (9R,10R)-9-acetoxy-8,8-dimethyl-9,10-dihydro-2H,8H-benzo[1,2-b:3,4-b']dipyran-2-one-10-yl ester (1), isobutyric acid (9R,10R)-9-hydroxy-8,8-dimethyl-9,10-dihydro-2H,8H-benzo[1,2-b:3,4-b']dipyran-2-one-10-yl ester (2), isobutyric acid (9R)-8,8-dimethyl-9,10-dihydro-2H,8H-benzo[1,2-b:3,4-b']dipyran-2-one-9-yl ester (10), 2-methylbut-(2Z)-enoic acid (3R)-5-methoxy-3,4-dihydro-2,2,8-trimethyl-6-oxo-2H,6H-benzo[1,2-b:5,4-b']dipyran-3-yl ester (11), and isobutyric acid (3R)-5-methoxy-3,4-dihydro2,2,8-trimethyl-6-oxo-2H,6H-benzo[1,2-b:5,4-b']dipyran-3-yl ester (12) by spectroscopic and chemical methods. The stereochemistry at the stereogenic centers was established by applying the Mosher ester methodology. The structures of 1 and 2 were corroborated by single-crystal X-ray diffraction studies. The phytotoxic activity of the isolated compounds was assessed on Amaranthus hypochondriacus, Echinochloa crus-galli, and Lemna pausicostata. The phytotoxins also modified the electrophoretic mobility of calmodulin from both bovine-brain and spinach.
