    摘要: 2'-Deoxy-2'-fluorocoformycin and 2'-deoxy-8-epi-2'-fluorocoformycin have now been synthesized by a multistage reaction via 3,5-di-O-benzoyl-2-deoxy-2-fluoro-α- and -β-D-ribofuranosyl bromide. Also 2'-deoxy-2'-epi-2'-fluorocoformycin and 2'-deoxy-8,2'-diepi-2'-fluorocoformycin have been synthesized from 3,5-di-O-benzoyl-2-deoxy-2-fluoro-α-D-arabinofuranosyl bromide by a multistage reaction. These four 2'-fluorocoformycin derivatives are novel compounds and have a potent enzyme inhibiting activity against adenosine deaminase. In particular, they are useful for treating acute lymphocytic leukemia in virtue of the above activity. Other novel compounds also obtained include various intermediates useful for the synthesis of the above derivatives.
