Synthesis of 3-(Alkylamino)-, 3-(Alkoxy)-, 3-(Aryloxy)-, 3-(Alkylthio)-, and 3-(Arylthio)-1,2,4-triazines by Using a Unified Route with 3-(Methylsulfonyl)-1,2,4-triazine

, 2016
In our attempts to synthesize 3‐(alkylthio)‐ and 3‐(alkoxy)‐1,2,4‐triazines without substituents at the 5‐ or 6‐position, the synthesis of their anticipated precursor 3‐(methylsulfonyl)‐1,2,4 triazine was also optimized.

A one-pot, three-component, microwave-promoted synthesis of 2-amino-substituted 7-amino-1,2,4-triazolo[1,5-a][1,3,5]triazines

, 2013
A new, efficient, catalyst-free, one-pot, three-component method for the synthesis of 2-amino-substituted 7-amino-1,2,4-triazolo[1,5-a][1,3,5]triazines using 3,5-diamino-1,2,4-triazoles, cyanamide, and triethyl orthoformate is developed.
