The title compounds (17 and 23) were prepared by coupling 3,4-di-O-acetyl-2,6-dideoxy-2-fluoro-alpha-L-talopyranosyl bromide (15) with daunomycinone. The key step in the preparation of 15 was the epoxide-ring opening of methyl 2,3-anhydro-4-O-benzyl-6-deoxy-alpha-L-gulopyranoside with KHF2 in ethylene glycol, whereupon 2-fluoro-alpha-L-idopyranoside was obtained. Compounds 17 and 23 showed strong antitumor

Synthesis of the anthracycline anticancer agent, 14-O(β-alanyl-N-HC)-7-O (2',6'-dideoxy-2'-fluoro-α-L-talopyranosyl) Adriamycinone (DA-125- 14 C) labeled with carbon-14 regiospecifically for ADME (absorption, distribution, metabolism, and excretion) studies is described. Unlabeled 7-O(2',6'-dideoxy-2'-fluoro-α-L-talopyranosyl) adriamycinone (Dong-A Pharm. Lot MI-8008)(B-1) was employed as the starting
