## Abstract Reaction of chloroglyoxime 1 with aryl isocyanates yielded monocarbamates 3, and chlorooxime functional group was unchanged. The 1,3βcycloaddition of nitrile Nβoxides generated from 3 to methyl methacrylate gave isoxazole derivatives 5. Compounds 5 were also obtained by carbamoylation o
