Article abstract of DOI:10.1039/P19820000473

Reaction of the 6-methyl-1,3-oxazine-2,4-diones (1) and (2) with hydrazine hydrate at room temperature gave the 6-hydroxy-5,6-dihydrouracils (7a) and (8a).The structures of the products were determined by 15N n.m.r. analysis.The mechanism of the ring transformation of 1,3-oxazines into pyrimidines and pyrazoles is discussed.
