摘要: 利用含P_H键苯并磷杂环化合物与醛的反应,设计合成了新的A2羟基膦酸衍生化喹唑啉酮含磷类似物2或Ò,并研究了含P_C_O结构的2或Ò转化为含P_O_C结构的3或Ó的重排反应,目标化合物的结构经NMR,IR,MS和元素分析证实.结合NMR数据,探讨了化合物2因具有C*和P*两个手性中心而产生的非对映异构现象及其氢谱特征.对所合成的化合物进行了初步生物活性测试,发现部分化合物具有很好的抗植物病原真菌(苹果斑点落叶病菌)作用和一定的人体疱疹病毒抑制活性.

Abstract: Aseries of 1-methoxycarbonylmethyl 2-(1-substituted hydroxymethyl) 3-benzyl 2,4-dioxo-1,3,2-benzodiazaphosphorins 2 or Ò and their rearrangement reaction products 3 or Ó have been synthesized by the reaction of aldehydes and P_Hreagent. Their structures were confirmed by elemental analysis, NMR, IRand MS. On the basis of NMRanalyses, we studied the diastereoisomerism phenomenon of the products 2 or Ò and the rearrangement reaction by which the products 3 or Ó were formed. The results of preliminary bioassay show that some of the target compounds have good in vitro activity against HSV-1 and (or) excellent fungicidal activity.

Key words: Quinazolone analogues containing phosphorus, Diastereoisomerism, Rearrangement reaction, Biological activity
