✦ Synopsis

During the course of our investigation of the synthesis of oic-triasoles by reacting a-keto-and a-ester phosphorus ylides with acyl asides and ethyl asidoformate (1 + 2 + z), we found that the N-l substituted triasoles,isomerised to the N-2 substituted triasoles (1 + A) under the basic reaction conditions. A description of this phenomenon is the subject of this communication.
