  新型除草剂4-羟基-3-（2-苯氧基乙酰基）-吡喃-2-酮衍生物的设计，合成及作用方式评价

  摘要：

  为了开发含有β-三酮基序的新型除草剂，设计并合成了一系列4-羟基-3-（2-苯氧基乙酰基）-吡喃-2-酮衍生物。生物测定结果表明，即使剂量为187.5 g ha –1，化合物II15也具有良好的芽前除草活性。此外，与商业除草剂2,4-二氯苯氧基乙酸（2,4-D）相比，化合物II15的杂草控制范围更广，并且对小麦和玉米具有良好的农作物安全性。当以375 g ha –1施用时在出苗前的条件下，表明其作为除草剂的巨大潜力。更重要的是，研究化合物II15的分子作用方式表明，新的三酮结构是其相应的苯氧乙酸生长素除草剂的除草剂，其除草机理与2,4-D相似。目前的工作表明4-羟基-3-（2-苯氧基乙酰基）-吡喃-2-酮基序可能是潜在的铅结构，用于进一步开发新型的生长素型除草剂。

  cobaloxime to produce olefins and H2. This operationally simple method enables direct dehydrogenation of readily available chemical feedstocks to diversely functionalized olefins. For example, we demonstrate, for the first time, the oxidant-free desaturation of thioethers and amides to alkenyl sulfides and enamides, respectively. Moreover, the system’s exceptional site selectivity and functional group

  脂肪族催化脱氢 (CDA) 在有机合成中的价值在很大程度上仍未得到充分探索。已知的均相 CDA 系统通常需要使用牺牲氢受体（或氧化剂）、贵金属催化剂和苛刻的反应条件，因此将大多数现有方法限制为非或低官能化烷烃的脱氢。在这里，我们描述了一种可见光驱动的双催化剂系统，该系统由廉价的有机光氧化还原和贱金属催化剂组成，用于室温、无受体 CDA (Al-CDA)。该过程由光激发的 2-氯蒽醌引发，涉及脂肪族的 H 原子转移 (HAT) 形成烷基自由基，然后与钴肟反应生成烯烃和 H 2. 这种操作简单的方法能够将容易获得的化学原料直接脱氢成多种官能化的烯烃。例如，我们首次证明了硫醚和酰胺在无氧化剂条件下分别脱饱和为烯基硫醚和烯酰胺。此外，14 种生物相关分子和药物成分的后期脱氢和合成说明了该系统卓越的位点选择性和官能团耐受性。机理研究揭示了双重 HAT 过程，并提供了对反应性和位点选择性起源的见解。

As a continuous work to discover novel crop selective HPPD inhibitor, a series of 2-(aryloxyacetyl)cyclohexane-1,3-diones were rationally designed and synthesized by an efficient one-pot procedure using N,N′-carbonyldiimidazole (CDI), triethylamine, and acetone cyanohydrin in CH2Cl2
