  新型植物活化剂支架的发现：从水杨酸到苯并三唑

  摘要：

  摘要从水杨酸（SA）和相关的商业化植物活化剂开始，基于分子三维形状和药效团相似度比较（SHAFTS），预测了一种新的铅化合物苯并三唑，并设计和合成了一系列苯并三唑衍生物。生物测定表明，苯并三唑在体内对多种疾病（包括真菌和卵菌）具有高活性，但在体外则无活性。并且在1'-位和5'-位引入适当的基团对于该活性是有利的。因此，它们具有被开发为新型植物激活剂的潜力。

  An original approach to achieve the C(sp2)–H azolation of cyclic aldonitrones mediated by Selectfluor® has first been employed. By exploiting a metal-free, visible-light-promoted cross-dehydrogenative C–N coupling reaction between model aldonitrones, 2H-imidazole 1-oxides, and NH-containing azoles, a series of novel azaheterocyclic derivatives have been obtained in yields up to 94%. The elaborated
