Synthesis and Properties of 4-Benzyloxyimino- and 4-Hydroxyimino-1,3-dioxan-2-ones

Under suitable conditions the reaction of N-benzyloxy-3-hydroxycarboxamides 7 with phosgene produces 3-benzyloxy-5,6-dihydro-2H-1,3-oxazine-2,4(3H)-diones 8 and 4-benzyloxyimino-1,3-dioxan-2-ones 6.Hydrogenolysis of 6 gives 4-hydroxyimino-1,3-dioxan-2-one

Cyclic Carbonylation of 3-Hydroxycarbohydroxamic Acids with 1,1'-Carbonyldiimidazole

The reaction of 3-hydroxycarbohydroxamic acids 3 with 1,1'-carbonyldiimidazole produces as a function of the substitution of 3 heterocycles of type 1, 4, and 5.In the presence of imidazole the 3-(2-hydroxyalkyl)-1,4,2-dioxazol-5-ones 1 undergo rearrangeme
