    ABSTRACT The heterocyclizations from various methyl (2-nitrobenzoyl)carbamates to substituted quinazoline-2,4(1H,3H)-diones under hydrogenation conditions were investigated in this study. In the presence of p-toluenesulfonic acid monohydrate in methanol, various quinazoline-2,4(1H, 3H)-diones were obtained in good to excellent yields within 12 h. The reaction was proposed to proceed through the cascade
    摘要 本研究研究了在氢化条件下从各种(2-硝基苯甲酰基)氨基甲酸甲酯到取代喹唑啉-2,4(1H,3H)-二酮的杂环化反应。在甲醇中存在对甲苯磺酸一水合物的情况下,在 12 小时内以良好至极好的收率获得了各种喹唑啉-2,4(1H, 3H)-二酮。建议该反应通过硝基还原和缩合的级联反应进行。图形概要

  • Synthesis and antihyperglycemic activity of suitably functionalized 3H-quinazolin-4-ones☆
    作者:Vishnu Ji Ram、Farhanullah、Brajendra K Tripathi、Arvind K Srivastava
    DOI:10.1016/s0968-0896(03)00142-1
    日期:2003.5.29
    A series of 2-sec-amino-3H-quinazolin-4-ones (4a-p) and 4-sec-amino-2-chloroquinazolines (5a-b) have been synthesized by nucleophilic substitution reaction of 2-chloro-4(3H)-quinazolones (3) and 2,4-dichloroquinazolines (2) with amines, respectively. Most of the synthesized compounds were evaluated for antihyperglycemic activity but only 4a,b,d,j,o displayed significant reduction in blood glucose level in streptozotocin and sucrose loaded rat models.
