REACTION OF ISOCYANIC ACID AND ISOCYANATES WITH DIKETENE. PREPARATION OF 2H-1,3-OXAZINES, 4-PYRONES, AND 2-PYRIDONES

Reaction of diketene with isocyanic acid gave the expected product, 2,4-dioxo-6-methyl-3,4-dihydro-2H-1,3-oxazine (2), but with aryl isocyanates gave 3-aryl-2,4-dioxo-6-methyl-3,4-dihydro-2H-1,3-oxazines (3), 3-(arylcarbamoyl)-2,6-dimethyl-4-pyrones (4), and 3-acetyl-1-aryl-4-hydroxy-6-methyl-2-pyridones (5) depending on the reaction conditions.
