✦ Synopsis

Methylation of 5-Isonitroso-1,3-dioxine-4,6-diones with Diazomethane and Some Reactions of Their Products.

-Methylation of the title isonitrosodioxinediones (I) with diazomethane affords O-methylated (III) and N-methylated products (IV) together with the cyclic nitrone (V) as a minor product. N-oxide (IV) reacts with triphenylphosphine to phosphonium betaines (VII) whereas irradiation provides the novel spiro compounds (VIII) via oxaziridine intermediates. -(KATAGIRI, N.;
