Abstract
Abstract 5,7-Dimethyl[1,2,4]triazolo[1,5-a]pyrimidinio-3-phenacylide ( 3 ) generated by the reaction of an iminium salt ( 2 ) with 1 eq. of triethylamine, underwent a new thermal ring cleavage of the triazole moiety to give the pyrimidine derivative. However reaction of 2 with 2 eq. of triethylamine afforded the 2-iminooxazoline derivative. The iminooxazoline reacted with nucleophiles such as alcohols or amines to give imidazoles.
