ABSTRACT:
A method of converting pure α-anomer or β/α-anomer mixtures of 1,2,3,5-tetra-O-acetyl-L-ribofuranose to methyl-1-(2,3,5-tri-O-acetyl-β-L-ribofuranosyl)-1,2,4-triazole-3-carboxylate an intermediate for levovirin, as well as, the novel pure α-anomer, alpha 1,2,3,5-tetra-O-acetyl-L-ribofuiranose, are useful in manufacturing levovirin.
