Syntheses of Novel Antimicrobial Compounds : Pyrazolo [5, 1-b] thiazole, Imidazo [1, 2-b] pyrazole, and Thiazolo [3, 2-b] dihydro-1, 2-diazepine

SYNTHESIS OF SOME IMIDAZO [ I , 2-b] [l , 2,4] TRIAZINE AND N-ALKYLATED IMIDAZO [l , 2-b] [1 , 2,4]-TRIAZINES

A number of 3-amino-1, 2, 4-triazin-5 (2H)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4H)-ones (2). These compounds were reacted further with a - haloketones to yield N-alkylated products (3).

SYNTHESIS OF OXAZOLO [3, 2-b] 1, 2, 4- TRIAZINES A NOVEL HETEROCYCLIC SYSTEM

The synthesis of 6- methyl- 2- phenyl- 7H- oxazolo [3,2-b] 1,2,4-Triazine- 7-one (6, R=Ph) and its 2-P- bromophenyl analogue to the two members of a new heterocyclic system is described

synthesis of some imidazo [ i , 2-b] [l , 2,4] triazine and n-alkylated imidazo [l , 2-b] [1 , 2,4]-triazines

a number of 3-amino-1, 2, 4-triazin-5 (2h)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4h)-ones (2). these compounds were reacted further with a - haloketones to yield n-alkylated products (3).
