- Effects of co-reagents on the reactions of alcohols with 6-methyl-1,3-oxazin-2,4(3H)-diones
-
Primary alcohols in the presence of Triton-B react preferentially at C-6 of N-alkyl-6-methyl-1,3-oxazin-2,4(3H)-diones (1a, 1b) to give corresponding N-alkyl-3-alkoxybut-2-enamides (2) but react at C-2 of 1,3-oxazin-2,4(3H)-dione (1c) to give N-acetoacetylcarbamates (4).The modes of these reactions have been rationalised.

-
Primary alcohols react at C-6 of 3-alkyl-6-methyl-1,3-oxazine-2,4(3H)-diones(2) in the presence of Triton-B or potassium thiocyanate to give N-alkyl-3-alkoxybuten-2-amides(4).
