Irradiation of 4-methyl-2-phenyl-1,3-oxazin-6-one, 1, yields a photochemical equilibrium between 1 and 2-methyl-4-phenyl-1,3-oxazin-6-one, 2.The isomerization proceeds through two intermediates, the oxa-azabicyclohexenones 3 and 4, both of which can be observed spectroscopically (ir, uv, 1H nmr) at low temperature.

Alkylation of ethyl 3-amino-2-butenoate, 1, with methyl iodide, ethyl iodide, and benzyl bromide gave both C- and N-alkylated products (contrary to earlier findings) the ratio of which was determined by GLC.Methylation of 1 was studied under different con
