The reaction of 6-amino-5-formyl (or acetyl) uracils (4) possessing a phenyl group at the 1-position with caustic alkali resulted in Dimroth rearrangement to give 6-anilino-5-formyl (or acetyl) uracils (5). This is the first example of Dimroth rearrangeme
Pyrimidine Derivatives and Related Compounds. XLVI. Thermal and Photochemical Transformation of 5-Substituted 6-Azido-1,3-dimethyluracils into Fused Pyrimidines such as Isoxazolopyrimidines, Pyrazolo-pyrimidines, and Pyrimido-t
