The sulfhydrolysis of the glycolimidates 3 affords 2-hydroxy thiocarboxylic O-esters (4), which on treatment with phenylhydrazine give glycolohydrazonates of type 5.Under suitable conditions the reaction of 5 with phosgene or 1,1'-thiocarbonyldiimidazole produces 3,6-dihydro-2H-1,3,4-oxadiazin-2-ones(thiones) 6 as stable compounds. - Keywords: 2-Hydroxythiocarboxylic O-Esters, 2-Hydroxycarbohydrazono Esters, Phosgene, 1,1'-Thiocarbonyldiimidazole, 5-Alkoxy-3,6-dihydro-2H-1,3,4-oxadiazin-2-ones(thiones)

Sulfhydrolysis of the glycolimidates 4 affords 2-hydroxy thiocarboxylic O-esters 5, which on treatment with hydroxylamine give 2-hydroxy carboximic esters 3.The (E)/(Z) isomer distribution of 3 depends largely on the substituents at C-2 and can be affecte
