were synthesized: 2-phenyl-7-hydroxy-4H-3,l-benzoxazin-4-one (Dianthalexin) and 2-(2-hydroxybenzoyl)-amino-4-methoxybenzoic acid (Dianthramide A). The first one was obtained by using potassium t-butoxide in dimethylformamide to prevent its heterocycle opening. Five novel other analogous compounds were also prepared.
合成了两种植物抗毒素,它们是以前从被寄生疫霉疫霉感染的康乃馨中分离出来的:2-苯基-7-羟基-4 H -3,1-苯并恶嗪-4-酮(Dianthalexin)和2-(2-羟基苯甲酰基)-氨基-4-甲氧基苯甲酸(去甲酰胺A)。第一个是通过在二甲基甲酰胺中使用叔丁醇钾防止其杂环打开而获得的。还制备了五种新的其他类似化合物。
