Advances in chemistry and biological activity of fluorinated 1,3,5-triazines

open access: yes, 2007
The substitution of hydrogen by fluorine as bioisosteric replacement has been practised widely in agricultural and medicinal chemistry. This has led to the discovery of many pesticides and therapeutically useful chemical entities.

Synthesis of C-(β-D-glucosaminyl)-1,2,4-triazines

open access: yes, 2018
In my diploma thesis I studied the syntheses of C-glucosaminyl-1,2,4-triazines and 1,2,4-triazin-5(4H)-ones. For the preparation of the target heterocycles C-(2-deoxy-2-phthalimido-3,4,6-tri-O-acetyl-β-D-glucopyranosyl)formamidrazone was prepared first ...

Synthesis of 5,7-Diamino[1,2,4]triazolo[1,2-a][1,3,5]triazines via Annulation of 1,3,5-Triazine Ring onto 3(5)-Amino-1,2,4-trizoles

open access: yes, 2007
The 5,7-diamino[1,2,4]triazolo[1,5-a][1,3,5]triazines were synthesized by cyclocondensation of 3(5)-amino-1,2,4-triazoles with cyanoguanidine. The substituted 3(5)-amino-1,2,4-triazoles were prepared from corresponding hydrazides and S-methylisothiourea ...
