5-Alkoxy and 2-alkoxyoxazoles were shown to react with NN, CN or CO dienophiles to form products that in most cases can be explained to result from a Diels-Alder addition, or by nucleophilic attack of the oxazole on the dienophile, followed by rearrangement. The products are triazolines, imidazolines or oxazolines respectively. Relative reactivitles were established and mechanistic pathways discussed
研究表明5-烷氧基和2-烷氧基恶唑与N,N,C orN或CO亲二烯体反应形成产物,在大多数情况下,这可以解释为由Diels-Alder加成或恶唑的亲核攻击导致在亲双烯体上,然后重排。产物分别是三唑啉,咪唑啉或恶唑啉。建立了相对反应性并讨论了机理途径。
