## Abstract A number of new [(pyrazolโ4โyl)methylene]hydrazonoโ2,3โdihydrothiazole derivatives, their sugar hydrazones and __N__โglycosides were synthesized. Furthermore, __N__โsubstituted oxygenated alkyl and hydroxyl derivatives and 1,3,4,โoxadiazoline acyclic nucleoside analogs were prepared. Th
The reaction of 3-aryl-3-thiosemicarbazides 1a-d with carbon disulfide in alkaline medium affords the nonisolable sulfide salts 2a-d. The latter undergo in situ heterocyclization with some โฃ-halogenated compounds, e.g., 3a,b and 13, to afford polyfunctionally substituted 2,3-dihydrothiazoles 4a-e an
