  Synthesis of benzylaminopyrimidines and their fungicidal activities against wheat brown rust and barley powdery mildew

  摘要：

  Members of a new class of fungicide containing benzyl-aminopyrimidine as a core structure were synthesized and their fungicidal potencies against wheat brown rust, Puccinia recondita, and barley powdery mildew, Erysiphe graminis, were assessed. Among these fungicides, N-(fluoroalkoxy or fluorophenoxybenzyl)-4-pyrimidinamines showed notable preventive activities. The potency of the new pyrimidines was increased when a difluoromethoxy or tetrafluorophenoxy group was introduced at the 4- or 3-position of the phenyl moiety and a methyl or ethyl group was introduced at the benzyl position. Structure-activity relationships are discussed. (C) 1998 Society of Chemical Industry.

  Intermolecular C–H difluoromethoxylation of (hetero)arenes remains a long-standing and unsolved problem in organic synthesis. Herein, we report the first catalytic protocol employing a redox-active difluoromethoxylating reagent 1a and photoredox catalysts for the direct C–H difluoromethoxylation of (hetero)arenes. Our approach is operationally simple, proceeds at room temperature, and uses bench-stable

  （杂）芳烃的分子间CH-H二氟甲氧基化在有机合成中仍然是一个长期存在且尚未解决的问题。在这里，我们报道了第一个使用氧化还原活性二氟甲氧基化试剂1a和光氧化还原催化剂对（杂）芳烃进行直接CHH二氟甲氧基化的催化方案。我们的方法操作简便，可在室温下进行，并使用稳定的试剂。其温和的反应条件可耐受多种官能团和生物相关分子，从而突出了其合成用途。实验和计算研究表明，单电子转移（SET）从激发的光氧化还原催化剂到1a，形成释放OCF 2的中性自由基中间体仅氢自由基。将该自由基加到（杂）芳烃上，得到二氟甲氧基化的环己二烯基，其被氧化和去质子化，得到二氟甲氧基化的产物。
