Notes:
Reaction of chloroglyoxime 1 with aryl isocyanates yielded monocarbamates 3, and chlorooxime functional group was unchanged. The 1,3-cycloaddition of nitrile N-oxides generated from 3 to methyl methacrylate gave isoxazole derivatives 5. Compounds 5 were also obtained by carbamoylation of 3-formyl-4-hydro-5-methyl-5-methoxycarbonylisoxazole oxime 6.The selectivity of chloroglyoxime carbamoylation and the poor reactivity of chlorooxime group is general. Examples, involving another oximes and their halogeno derivatives are given.
