Recently reported syntheses of 1,3-benzoxazepines and 1,3,4-benzoxadiazepin-5-ones were reinvestigated and found to produce, instead, 2-(2-hydroxyphenyl)-1,3,4-oxadiazoles and 5-(2-hydroxyphenyl)-1,3-oxazoles, respectively.
对最近报道的 1,3-苯并氧氮杂卓和 1,3,4-苯并氧二氮杂卓-5-酮的合成方法进行了重新研究,发现它们分别生成了 2-(2-羟基苯基)-1,3,4-恶二唑和 5-(2-羟基苯基)-1,3-
恶唑。
