  • A novel approach to biologically relevant oxazolo[5,4-d]pyrimidine-5,7-diones via readily available diazobarbituric acid derivatives
    作者:Martha Gecht、Grigory Kantin、Dmitry Dar'in、Mikhail Krasavin
    DOI:10.1016/j.tetlet.2019.151120
    日期:2019.10
    from 1,3-disubstituted barbituric acids to biologically relevant oxazolo[5,4-d]pyrimidine-5,7-diones was developed that features sulfonyl-azide-free (SAFE) diazo transfer and Rh2(esp)2-catalyzed cycloaddition of the resulting 5-diazobarbituric acids with aliphatic and aromatic nitriles. Besides being shorter compared to the previously described approaches, the method allows introduction of alkyl substituents
    从1,3-二取代的巴比妥酸生物学上相关的恶唑并[5,4- d ]嘧啶-5,7-二酮的另一种途径被开发出来,其特征在于无磺酰叠氮SAFE)的重氮转移和Rh 2(esp)2催化的5-重氮巴比妥酸与脂族和芳族腈的环加成反应。除了比先前描述的方法短之外,该方法还允许在稠合杂环系统的1,3-恶唑环上引入烷基取代基。
  • Ring closure reactions of azidouracils to oxazolo- and isoxazolopyrimidines
    作者:Dang Van Tinh、Wolfgang Stadlbauer
    DOI:10.1002/jhet.5570330404
    日期:1996.7
    presence of polyphosphoric acid leads either to oxazolo[5,4-d]pyrimidine-5,7-diones 5 (by reaction with benzoic acid 2a) or to isoxazolo[3,4-d]pyrimidine-4,6-diones 7 (by reaction with aliphatic carboxylic acids 2b,c). 5-Benzoylpyrimidinetriones 12 could be shown to cyclize to isoxazolo[5,4-d]pyrimidine-4,6-diones 15 by chlorination with phosphorus pentachloride and subsequent reaction with sodium azide.
    在多磷酸存在下对6-azidouracils 1的热解会生成恶唑并[5,4- d ]嘧啶-5,7-二酮5(通过与苯甲酸2a反应)或异恶唑并[3,4- d ]嘧啶-4,6-二酮7(通过与脂族羧酸2b,c反应)。通过用五氯化磷化并随后与叠氮反应,可以显示5-苯甲酰基嘧啶三酮12环化成异恶唑并[5,4 - d ]嘧啶-4,6-二酮15。
  • Synthesis of 9-substituted 8-phenyltheophyllines.
    作者:SADAO NISHIGAKI、JUNKO SATO、KAYOKO SHIMIZU、KEITARO SENGA
    DOI:10.1248/cpb.28.1905
    日期:——
    Various 9-substituted 8-phenyltheophyllines (III) were prepared in two steps starting from 5, 7-dimethyl-2-phenyloxazolo [5, 4-d] pyrimidine-4, 6 (5H, 7H)-dione (I). Thus, treatment of I with amines afforded 5-(N-substituted benzamidino)-1, 3-dimethylbarbituric acids (II). The reaction of II with thionyl chloride or phosphorus oxychloride gave III.
    从 5,7-二甲基-2-苯基噁唑并[5,4-d] 嘧啶-4,6 (5H,7H)-二酮(I)开始,分两步制备了各种 9-取代的 8-苯基茶碱(III)。因此,用胺处理 I 可以得到 5-(N-取代苯甲酰胺基)-1,3-二甲基巴比妥酸(II)。II 与亚硫酰氯或氧反应后得到 III。
  • 5,5’-Bipyridyl-2,4,6,2’,4’,6’-hexaone Derivatives (Hydurilic Acids): Syntheses, Mechanism of C-C-Bond Formation and Properties of the Dimeric Barbituric Acid Derivatives
    作者:Christa E. Müller、Carolin Roegler、Jörg Hockemeyer
    DOI:10.3987/com-08-s(d)37
    日期:——
    A series of hydurilic acid derivatives (5,5'-bipyrimidinyl-2,4,6,2',4',6'-hexaones) including several new derivatives was synthesized from 5,6-diaminouracils. Mechanisms for their formation are proposed and discussed. Furthermore, a new method for the preparation of pyrimidine-2,4,5,6-tetraone-5-oxime derivatives (violuric acids) was found starting from 5-amino-6-nitrosouracils.
