Synthesis of 5-Chloro-l-(2, 3-Orisopropylidene-4-keto Rhamnopyranosyl)-uracil

Abstract Syntheses of 5-chloro-l-C2, 3, 4-tri-0-acetyl-αa-L-rhamnopyrano-syl)-uracil (1), 5-chloro-l-(a-L-rhamnopyranosyl)-uracil (2), 5-chloro-l (2, 3-Oisopropylidene-α-L-rhamnopyranosyl)-uracil (3), and 5-chloro-l-(2, 3-O-isopropylidene-4-Tceto-rhamnopyranosyl)-uracil (4 are reported. Oxidation of 3 to 4 was effected using pyridinium chlorochromate.
