Synthesis of Some Novel N-Ribosyl-1,2,4-Triazin-6(1H)-/Ones or Thiones as Potential Antibacterial and Antifungal Chemotherapeutics
摘要:
Ribosylation of 3-aryt-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 spectroscapically.

The 1-(2,3,4,6-tetra-O-acetyl-beta-D-galactopyranosyl)-3-aryl-5-benzyl (or substituted benzyl)-1,2,4-triazin-6(1H)-/ones or thiones were prepared via galactosidation of 3-aryl-5-benzyl (or substituted benzyl)-1,2,4-triazin-6(1H)-/ones or thiones with 2,3,4,6-tetra-O-acetyl-alpha-D-galactopyranosyl bromide. The structure of the new galactosyl derivatives was based on both spectroscopic and chemical
