THE METHYLENE BLUE-SENSITISED PHOTO-OXIDATIVE REARRANGEMENT TO 5-HYDROXYPYRIMIDINES OF SOME 3-ACYL-5-ARYL-4-BENZALAMINO-2-METHYLPYRROLES

A series of Shiff bases derived from para-substituted benzaldehydes and from 3-alkoxycarbonyl and 3-acyl-4-amino-5-aryl-2-methylpyrroles were submitted to methylene blue-sensitised photo-oxidation.Ring fission of the pyrrole ring with formation of enamidonitriles occurred in the case of the 3-alkoxycarbonyl derivatives, while a rearrangement to 4-aroyl-2-aryl-5-hydroxy-2-methylpyrimidines took place in the case of the 3-acyl derivatives.In one case the pyrimidine structure was confirmed by X-ray diffraction.
