摘要
通过2,4,6,8,10-五氯-6-硫-12H-双苯并[1,3,2]二氧磷杂八环分别与四氢吡咯、六氢吡啶、吗啉、吡咯、咪唑和1,2,4-三唑反应,得到了6个收率良好的标题新化合物。其结构经^1H、^13C、^31P NMR和元素分析确认。初步杀菌活性测定表明,化合物3c和3d在500μg/mL浓度下对水稻纹枯病菌Pellicularia sasakii的抑制率为48%-50%,其他化合物对供试菌的活性微弱。
Six novel compounds were synthesized in high yields by the reaction of 2,4,6, 8,10- pentachloro-12H-[ d, g ][ 1,3,2 ]-diozaphosphorcin-6-sulfoxide with tetrahydropyrrole, piperidine, morpholine, pyrrole, imidazole, and 1,2,4-triazole, respectively. Their structures were confirmed by elementary analysis, ^1 H,^13C, and ^31 p NMR data. Preliminary bioassay results showed that 3c and 3d have moderate inhibition rate （48%- 50% ）against Pellicularia sasakii at 500 μg/mL. Other compounds showed week inhibition effects against the tested fungi.
