Synthesis of some novel N-ribosyl-1,2,4-triazin-6(1H)-/ones or thiones as potential antibacterial and antifungal chemotherapeutics.

ABSTRACT

Ribosylation of 3-aryl-5-benzyl(or substituted benzyl)-1,2,4-triazin-6(1H)-/ones or thiones with 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose gave the corresponding 3-aryl-5-benzyl(or substituted benzyl)-1-(2,3,5-tri-O-benzoyl-beta-D-ribofuranosyl)-1,2,4-triazin-6(1H)-/ones or thiones. The structure of the new ribosides was confirmed chemically and spectroscopically.
