A series of novel 2-cyanoacrylatescontaining an isoxazole moiety were designed and synthesized. Their structures were characterized by 1H NMR and elemental analysis (or high-resolution mass spectrometry). Their herbicidal activities against four species were evaluated, and the results indicated that some of the title compounds showed excellent herbicidal activities against rape and amaranth pigweed
设计并合成了一系列含有异恶唑部分的新型2-氰基丙烯酸酯。它们的结构通过1 H NMR和元素分析(或高分辨率质谱)表征。评价了它们对四种物种的除草活性,结果表明,即使在75 g / ha的剂量下,某些标题化合物在出苗后处理中也表现出优异的对油菜和a菜杂草的除草活性。

We report a new strategy that translates indoles and related heterocycles into diverse 3D analogs by dearomative hydrocarboxylation. The transformation is highly chemoselective, broad in scope, operationally simple, and readily amenable to high-throughput experimentation (HTE).
我们报告了一种新策略,通过脱芳烃加氢羧化将吲哚和相关杂环化合物转化为多种 3D 类似物。该转化具有高度化学选择性、范围广泛、操作简单且易于进行高通量实验(HTE)。

日期:1992.5
Bromonitrite oxide can be generated homogeneously in water at acidic pH, allowing efficient [3 + 2] cycloaddition with water soluble olefins and acetylenes. Allylammonium salts react with high regioselectivity and without the need for N-group protection.
