Polyfused heterocyclic systems derived from 4-amino- 3-aryloxymethyl -5-mercapto-s-triazoles

ABSTRACT

2-aryloxymethyl-s-triazolo [5,1-benzo-[1,3] thiazine-9[H]-ones IIa-c and 1-aryloxymethyl-s-triazolo [4,3-d] [1,2,3,4] thiatriazoles IIIa-c were prepared from 4-amino-3-aryloxymethyl-5-mercapto- 1,2,4-triazoles la-c. Other new tricyclic systems; namely, 1-aryloxymethyl-s- triazolo [3,4-b] pyrrolo [1,2-d] [1,3,4] thiadiazepine derivatives IXa-c and XIa-b were synthesized by intramolecular electrophilic substitution of some 4-pyrrolyl-s- triazole derivatives. The structure of the products was established by IR and PMR spectral data
