It has been revealed that 1-azirines having an ester function at C can be synthesized by the thermally induced skeletal rearrangement of 5-alkoxyisoxazoles and 5-alkylmercaptoisoxazles. Characterization of the azirines obtained was made by chemical reactions as well as by spectrometry. A further thermal transformation of azirine esters into oxazole derivatives could not be found. Mass spectra of representative
已经发现,可以通过热诱导5-烷氧基异恶唑和5-烷基巯基异恶唑的骨架重排来合成在C具有酯官能的1-叠氮基。通过化学反应以及光谱法对获得的叠氮基进行表征。找不到将叠氮基酯进一步热转化为恶唑衍生物。借助分辨率质谱法对代表性的1-azirines的质谱进行了讨论,其在电子轰击下的行为与它们的化合价异构体5-烷氧基异恶唑的行为相关。
