Studies on epimeric-D-arabino- and -D-ribo-tetritol-1-yl-2-phenyl-2 h- 1,2,3-triazoles. Synthesis and anomeric configuration of 4-(α- and β-D- erythrofuranosyl)-2-phenyl-2 h-1,2,3-triazole C-nucleoside analogs

Treatment of 4-(D-arabino-tetritol-l-yl)-2-phenyl-2 H-1,2,3-triazole (1) with one mole equivalent of tosyl chloride in pyridine solution, afforded the C-nucleoside analogs, 4-(α-D-erythrofuranosyl)-2-phenyl-2 H- 1,2,3-triazole (2) in 25% yield, as well as the byproduct 4-(4-chloro-4-deoxy-D-arabino- tetritol-l-yl)-2-phenyl-2 H-1,2,3-triazole(3). Treatment of the epimeric 4- (D-ribo-tetritol-l-yl)-2-phenyl-2 H-1,2,3-triazole(8) with tosyl chloride in pyridine solution afforded the anomeric C-nucleoside analogs, 4-(β-D- erythrofuranosyl)-2-phenyl-2 H-1,2,3-triazole (9) in 23% yield. Similar treatment of 8 with trifluoromethanesulfonyl chloride in pyridine solution afforded 9. The structure and anomeric configuration of these compounds were determined by acylation, NMR, NOE, circular dichroism spectroscopy and mass spectrometry.

STUDIES ON 3-EPIMERIC 2-HEXULOSE PHENYLOSAZONES. STRUCTURE AND ANOMERIC CONFIGURATION OF THE 3,6-ANHYDRO-OSAZONE DERIVATIVES OBTAINED FROM D-arabino- AND D-ribo-2-HEXULOSE PHENYLOSAZONE

Dehydration of the 3-epimeric 2-hexulose phenylosazones D-arabino-hexulose phenylosazone or D-ribo-hexulose phenylosazone afforded 3,6-anhydro-D-ribo-hexulose phenylosazone (4) as the preponderant isomer from both.The identity of 4 was obtained by t.l.c., and by acylation followed by comparison of the products.Prolonged acetylation with acetic anhydride-pyridine, or by refluxing with acetic anhydride, afforded the same N-acetyldi-O-acetyl derivative.Refluxing 4 with copper sulfate, or the osotriazole with 20percent methanolic sulfuric acid, afforded the C-nucleoside analog, namely, 4-β-D-erythrofuranosyl-2-phenyl-1,2,3-osotriazole (7).The anomeric configurations of 4 and 7 were ascertained from the n.m.r. spectra of their isopropylidene derivatives.The mechanism of the dehydrative cyclization process and the mass spectra of two compounds were discussed.
