lsulfanyl-3,4-dihydro-pyrido[4,3-d]pyrimidine-8-carbonitriles , were synthesized via a facile annulation process in which formation of the pyrimidine ring proceeded smoothly by the regioselective attack of a formamidate group on a neighboring carbonyl group instead of a cyano group. Bioassay results indicated that these compounds showed significant herbicidal activity at a dose of 100 μg/mL on the
十五个新的3-取代的5-甲基-4-亚甲基-7-烷基硫烷基-3,4-二氢-吡啶并[4,3-d]嘧啶-8-腈 通过简单的环合方法合成了α,β,其中嘧啶环的形成通过在相邻的羰基而不是氰基上的甲酰胺基团的区域选择性攻击而平稳地进行。生物测定结果表明,这些化合物在油菜和n草的根部以100μg/ mL的剂量显示出显着的除草活性。在此外,这些化合物的一些显示杀真菌活性。J.杂环化学,(2009)。
