N-acylisoxazol-5-ones are converted into the corresponding 2-substituted oxazoles by photolysis at 300 or 254nm, or by flash vacuum pyrolysis. The former procedure is favoured for isoxazolones with electron withdrawing groups at C-4, and pyrolysis for all others.
通过在300或254nm处进行光解或通过快速真空热解将N-酰基异恶唑-5-酮转化为相应的2-取代的恶唑。前一种方法适用于在C-4具有吸电子基团的异恶唑酮,而对于所有其他方法均热解。
