Acetyl methyl nitrolic acid

Acetyl methyl nitrolic acid (VI) is the well known product of the reaction of HN03 on acetone. After loosing HN02 it condenses with acetylene to yield 3-acety-lisoxazole (VII). Through the same sequence of reactions it eventually forms IX. Dimerization of the nitrile oxide (VIII) yields diisoxazoylfuroxane (X).
