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

The first syntheses of the novel [1,2]thiaphospholo[4,5-e][1,2,4]triazine ring system, exemplified by the derivatives 3a-c have been accomplished by the action of Lawesson's reagent on the 5-arylmethyl-1,2,4-triazin-6-ones 1a-c, their thiones 2a-c or the Mannich bases 4-6. The structure of these new thiaphospholotriazines was established mainly by NMR, and X-ray structural analysis. (C) 1999 Elsevier Science Ltd. All rights reserved.

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.
