Adams platinum hydrogenation of Z-3-aryl-5,6-dihydro-5-(substituted)methylene-4H-1,2,4-oxadiazine (1a-f) proceeds very slowly through C-O bond fission to give N-(1-substitutedcarbonyl-2-propylidene)benzamide oxime derivative 2 as the main product.In the reaction of 5-(arylcarbamoyl)methylene analogues 1d-f, 5-(arylcarbamoyl)methyl-5,6-dihydro-3-phenyl-4H-1,2,4-oxadiazine (4) and N-aryl-3-hydroxybutanamide derivative 5 are also obtained as well as compound 2.
