%X Dimedone (6) was C-acylated with 4-(1&#8242;-methylethylideneaminooxy) butanoic acid (7), and the product (8) was hydrolysed to give 2-(5&#8242;,6&#8242;-dihydro-4&#8242;H-1&#8242;,2&#8242;-oxazin-3&#8242;-yl)- 5,5-dimethylcyclohexane-1,3-dione (3). The 2-(4&#8242;,5&#8242;-dihydroisoxazol-3&#8242;-yl) 1,3-dione (4) was obtained in <2% yield from dimedone anion and 3-nitro-2-isoxazoline (11).
