3-Formyl-5,5 -diisoxazol-3 -aldoxime

The reaction of diacetylene with cyanic acid (HCNO) proceeds at room temperature in the presence of sulfuric acid in aqueous methanol to give 3-formyl-5,5 -diisoxazol-3 -aldoxime (85) and 3,3 -diformyl-5,5 -diisoxazoldioxime (86), whose oxidation with potassium permanganate followed by esterification results in 3,3 -dicarbomethoxy-5,5 -diisoxazoles (87) (59G598). [Pg.180]
