Substituted derivatives of hexahydro-oxazolo[4,5-d]-1,2,3-triazoles, a new ring system, are described, and the crystal structure of one derivative is reported; on being heated they undergo a ring expansion providing a simple new route to the rare 1,3,4,5-oxatriazine ring.
描述了六氢-恶唑并[4,5- d ] -1,2,3-三唑的取代衍生物,一种新的环系统,并报道了一种衍生物的晶体结构。加热后,它们会发生扩环,为获得稀有的1,3,4,5-草三嗪环提供了一条简单的新途径。
