1-Benzyl-2,4,6-pyrimidinetrione (1) reacts at C-5 with aldehydes and the isolated products can easily undergo base-induced transformations by Michael addition. On the contrary,the action of POC13 or piperidine/AcOH on the title trione afforded pyrimido[4′,5prime;:4,5]furo[2,3-d]pyrimidine (16) and a dimer (17), respectively, which in turn, undergo cyclocondensation in Ac2O.
