Studies on condensation of chlorocarbonyl phenyl ketene with N-unsubstituted amides: Synthesis of some new 1,3-oxazin-6-ones
A series of 1,3-oxazin-6-one derivatives has been synthesized upon treatment of N-unsubstituted amides with chlorocarbonyl phenyl ketene under reflux in toluene for several minutes. In this simple way, 2,5-disubstituted derivatives of 1,3-oxazin-6-ones have been obtained in high yields.
