SYNTHESIS OF PYRAZOFURINS: FURTHER CORRELATIONS BETWEEN CONFIGURATION-CONFORMATION AND (1)H-N.M.R. DATA FOR C-(2,3-O-ISOPROPYLIDENEGLYCOFURANOSYL) DERIVATIVES

Methyl 4-(2,3-O-isopropylidene-5-O-trityl-α- and -β-D-ribofuranosyl)-3-oxobutanoate (5α and 5β) were prepared in good yield by reacting 2,3-O-isopropylidene-5-O-trityl-D-ribofuranose with 3-methoxycarbonylacetonylidenetriphenylphosphorane catalysed by ben
