The synthesis of novel coumarin[8,7-e][1,3]oxazine derivatives through a microwave-assisted three-component one-pot Mannich reaction is described in this study. All the target compounds were evaluated in vitro for their antifungal activity against Botrytis cinerea, Colletotrichum capsici, Alternaria solani, Gibberella zeae, Rhizoctonia solani, and Alternaria mali. The preliminary bioassays showed that
本研究描述了通过微波辅助三组分一锅法曼尼希反应合成新型香豆素[8,7- e ] [1,3]恶嗪衍生物。所有的目标化合物进行了评价体外它们对抗真菌活性灰霉病,辣椒炭疽病菌,链格孢菌,玉蜀黍赤霉,立枯丝核菌,和链格孢马里。初步的生物测定表明,5e,5m和5s表现出良好的抗真菌活性,最活跃的化合物为5m,具有\(\ hbox EC} _ 50} \)对葡萄灰霉病菌的值最低为2.1 nM 。
