2,3-二芳基-1,3-苯并噁嗪的合成及杀菌活性
Synthesis and Fungicidal Activities of 2,3-Diaryl-1,3-benzoxazines
【摘要】 在三甲基氯硅烷(TMSCl)的催化作用下,取代苯甲醛与邻(芳胺甲基)苯酚经N杂缩醛化反应生成了一系列2,3-二芳基-1,3-苯并噁嗪类化合物。目标化合物的结构用IR、1H NMR、13C NMR和元素分析等技术手段进行了表征。对所合成的化合物进行了初步杀菌活性测试,部分表现出良好的杀菌活性,化合物6e对菌核病菌的抑制活性为79.0%,化合物6a和6d均为74.8%,化合物6e对灰霉病菌的抑制活性为77.9%。
【Abstract】 A series of 2,3-disubstituted-1,3-benzoxazines was synthesized by trimethyl chlorosilane-catalyzed aza-acetalization of 2-arylaminomethyl phenols with aromatic aldehydes. The structures of the prepared compounds were characterized by FT-IR,1H NMR,13 C NMR and elemental analysis. Fungicidal activities of these compounds were also evaluated. Most of them exhibit good activities. Compound 6e shows 79% and77. 9% activity against S. Scleratotiorum and B. Cinérea,respectively. Compounds 6a and 6d exhibit 74. 8%activity against S. Scleratotiorum.
