The Chemistry of 1,2,4-Triazines, XIV. - Synthesis and Reactions of 5-Chloro-1,2,4-triazines

5-Chloro-1,2,4-triazines 4 are prepared from 1,2,4-triazin-5(2H)-ones 3 and transfered into 5-amino- (7), 5-cyano (8), and 5-(ω-alkinyloxy)-1,2,4-triazines (9). 7a-d are cyclized to imidazo1,2,4-triazines (10a-d).

Intramolecular Diels-Alder Reactions of 1,2,4-Triazines. Synthesis of Condensed Pyrimidines

1,2,4-Triazines with C5 tethered dienophilic side chains are sterically constrained to undergo intramolecular Diels-Alder reactions across the N2/C5 triazine positions; elimination of a nitrile from the intermediate adduct (N1 and C6 of the starting 1,2,4
