Thermolysis in solution of 5-azidoisoxazoles with formyl, acetyl or N-phenylimino in the 4-position led to the formation of bicyclic products; in the absence of such 4-substituents, ring-opening resulted and in two instances the expected nitrosoalkene intermediate was successfully trapped with 2,3-dimethylbuta-1,3-diene.
在5-叠氮基异恶唑与4-位的甲酰基,乙酰基或N-苯基亚氨基的溶液中热解导致形成双环产物。在没有这种4-取代基的情况下,导致开环,并且在两种情况下,预期的亚硝基烯烃中间体被2,3-二甲基丁-1,3-二烯成功地捕获。
