Syntheis of Some New Pyrazolotriazines, Pyrazolothiazines and Pyrazolopyrimidines

When the pyrazole derivatives 3a,b were treated with triethyl orthoformate, the pyrazolotriazinethiones 5a,b were obtained.These were S-alkylated to give compounds 6a-d.Treatment of 5a,b with hydrazine hydrate in ethanol afforded 7,8 respectively.Benzylid

METHYL N-ARYLDITHIOCARBAMATES: USEFUL REAGENTS FOR THE ANNELATION OF PYRIMIDINES AND 1,3-OXAZINES TO FIVE-MEMBERED HETEROCYCLIC RINGS

The reaction of methyl N-aryldithiocarbamates with ?-excessive heteroaromatic o-amino acid derivatives leads to the annelation of 4-oxo-2-thioxopyrimidines, 2,4-dioxopyrimidines or 2-arylamino-1,3-oxazines, depending on the reaction conditions.
