Synthesis and nematicidal activities of 1,2,3-benzotriazin-4-one derivatives containing benzo[d][1,2,3]thiadiazole against Meloidogyne incognita
摘要:
Based on the characteristic of benzo[d][1,2,3]thiadiazole to induce the systemic acquired resistance and improve the immunity of plants, benzo[d][1,2,3]thiadiazole was introduced into 1,2,3-benzotriazin-4-one, thirty-one novel 1,2,3-benzotriazin-4-one derivatives containing benzo[d][1,2,3]thiadiazole were designed and synthesized. Nematicidal activity showed that most of the synthesized compounds exhibited great inhibitory activity in vivo against Meloidogyne incognita at 20 mg/L. Among 31 tested compounds, A2 and A3 showed an excellent nematicidal activity with the inhibition rate of 50.4% and 53.1% at the concentration of 1.0 mg/L, respectively. The influence of substituent type and position was investigated. The relationship between structure and activity was also preliminary analyzed.
通过3-溴烷基-1,2,3-苯并三嗪-4-酮与2-氰基氨基-4-氧噻唑烷的钾盐反应,合成了一系列新的1,2,3-苯并三嗪-4-酮衍生物。碘化钾的存在。杀线虫试验在体内表明,它们中的一些表现出对所造成的黄瓜根结线虫病良好的防治效果南方根结线虫以10.0毫克的L的浓度,最高可达100%-1,表明1,2,3-苯并三-4-one衍生物可能是新型杀线虫剂的潜力。杀线虫活性受分子中取代基类型,取代位置和接头长度的组合影响。浓度为5.0和1.0 mg L –1时的抑制率数据还提供了具有高抑制活性的化合物。当在体外测试时,没有一个对隐孢霉菌有直接抑制作用。体内和体外数据之间显着差异的研究正在进行中。

Abstract To discover new chemotypes of nematicides with proper toxicological profiles, a series of novel 1,2,3-benzotriazin-4-one derivatives were synthesized and further bioevaluated. The bioassay results showed that most of the synthesized compounds were endowed with moderate to good control efficacy against Meloidogyne incognita at 10.0 mg/L in vivo . Among them, compounds 6k and 6p displayed 100%

An expedientsynthesis of benzo[c][1,2]dithiol-3-ones via metal-free denitrogenative transannulation of benzotriazinones is developed, which represents the first example of acid-mediated heteroannulation of benzotriazinones. This newly discovered reactivity of benzotriazinones enables the streamline synthesis of diverse benzo[c][1,2]dithiol-3-ones in decent yields by using sodium sulfide as the sulfur
通过苯并三嗪酮的无金属脱氮环环化,开发了苯并[ c ][1,2]二硫醇-3-酮的便捷合成方法,这是酸介导苯并三嗪酮杂环化的第一个例子。这种新发现的苯并三嗪酮的反应活性使得通过使用硫化钠作为硫源在简单的反应条件下能够以良好的产率简化合成各种苯并[ c ][1,2]二硫醇-3-酮。
