  • Synthesis of 8-Substituted Xanthines and Their Oxidative Skeleton Rearrangement to 1-Oxo-2,4,7,9-tetraazaspiro[4,5]dec-2-ene-6,8,10-triones
    作者:Hans Zimmer、Adel Amer、Frank M. Baumann、Michael Haecker、Christopher G. M. Hess、Douglas Ho、Hans J. Huber、Klaus Koch、K. Mahnke、Christian Schumacher、Robert C. Wingfield
    DOI:10.1002/(sici)1099-0690(199909)1999:9<2419::aid-ejoc2419>3.0.co;2-1
    日期:1999.9
    The synthesis of a number of 8-(dialkylamino)- and 8-alkoxyxanthines (3 and 6, respectively) is described. Treatment of 3 with m-chloroperoxybenzoic acid (m-CPBA) gave by a novel rearrangement 3-(disubstituted amino)-4,7,9-trimethyl-1-oxo-2,4,7,9-tetraazaspiro[4,5]dec-2-ene-6,8,10-triones 10. Also, the corresponding 3-alkoxy-subtituted spiro compounds 12 were obtained by an analogus treatment of 8-alkoxyxanthines
    描述了许多 8-(二烷基氨基)-和 8-烷氧基黄嘌呤(分别为 3 和 6)的合成。用间氯过氧苯甲酸 (m-CPBA) 处理 3,通过新的重排 3-(二取代氨基)-4,7,9-trimethyl-1-oxo-2,4,7,9-tetraazaspiro[4,5 ]dec-2-ene-6,8,10-triones 10。此外,相应的 3-烷氧基取代的螺环化合物 12 是通过类似处理 8-烷氧基黄嘌呤 6 获得的。试图阐明这种重排的初步机制8-[(二烷基氨基)甲基]咖啡因 7 在用 m-CPBA 处理时没有发生重排,但只产生了预期的 N-氧化物衍生物 16。这个结果似乎表明发生这种重排的必要结构元素是一个原子将一对未共享的电子连接到所研究的黄嘌呤的 8 位。

    The present invention refers to a method for controlling undesired vegetation at a plant cultivation site. The method comprises the steps of providing, at said site, a plant that comprises at least one nucleic acid comprising a nucleotide sequence encoding a wild-type hydroxyphenyl pyruvate dioxygenase or a mutated hydroxyphenyl pyruvate dioxygenase (mut-HPPD) which is resistant or tolerant to a coumarone-derivative herbicide and/or a nucleotide sequence encoding a wild-type homogentisate solanesyl transferase or a mutated homogentisate solanesyl tranferase (mut-HST) which is resistant or tolerant to a coumarone derivative herbicide, and then applying an effective amount of said herbicide to said plant cultivation site. The invention further refers to plants comprising mut-HPPD and to methods of obtaining such plants.

  • Photosensitized Oxidation of Oxopurines by Rose Bengal
    作者:Daniel H. Murgida、Pedro F. Aramendía、Rosa Erra Balsells

    日期:1998.10
    all cases photooxidations occur by a type II mechanism. Reactive and nonreactive 1O2 quenching rate constants by OP were determined in different solvents. Based on the correlations of the rate constants with different solvent parameters (α, β, ET[30], AN, DN, *,), the initial formation of an exciplex between 1O2 and OP is proposed that evolves to a zwitterionic transition state. Some reaction products
    研究了玫瑰红对氧代嘌呤 (OP) 作为咖啡因、茶碱、可可碱和 1,3,7-三甲基尿酸 (TMU) 的光敏氧化。在所有情况下,光氧化都是通过 II 型机制发生的。OP 在不同溶剂中测定了反应性和非反应性 1O2 淬灭速率常数。基于速率常数与不同溶剂参数(α, β, ET[30], AN, DN, *,)的相关性,提出了 1O2 和 OP 之间的激基复合物的初始形成,其演化为两性离子过渡态。对一些反应产物进行了表征,其中得到了 3-甲基-甲基-5-(甲胺)-1,5-脱氢乙内酰脲作为 TMU 的主要光氧化产物。提出了形成该反应产物和其他反应产物的反应机制。
