Addition of benzohydroxamic acid to propiolate esters gives 1,4,2-diozaxoles which originate, by base-catalysed ring opening with NaH, the isomeric O-vinyl hydroxamic acids. These compounds on thermolysis afford 1,3-oxazoles.
将苯并异羟肟酸加成丙酸酯得到1,4,2-二氮杂唑,其通过与NaH进行碱催化的开环而产生,该异构体是O-乙烯基异羟肟酸。这些化合物在热解后得到1,3-恶唑。
