Pyrolysis of 2-azido-naphthalene, -anthraquinone, and various azido-heterocycles in a mixture of polyphosphoric and acetic acid results in fusion of an oxazolo-moiety on to the parent system. The scope of this convenient oxazole synthesis in its widest sense is discussed.
在多磷酸和乙酸的混合物中2-叠氮基萘,蒽醌和各种叠氮基杂环的热解导致恶唑基部分融合到母体系统上。从最广泛的意义上讨论了这种方便的恶唑合成的范围。
