Hydrolysis in 2'-chloro-2'-deoxy nucleosides, -nucleotides and -polynucleotides to a rabinose-derivatives
Max-Planck-Institut für experimentelle Medizin, Abteilung Chemie D-3400 Göttingen, Hermann-Rein-Strasse 3, GFR
Received September 15, 1975. The rate of hydrolysis of 2'-chloro-2'-deoxycytidine and -uridine, and their 5'-phosphates, -diphosphates and polymers to the corresponding arabinocytidine and arabinouridine derivatives in the presence of Tris-HCl pH 8.9 is determined. This rate is highest for the nucleosides, less for the 5'-phosphates and 5'-diphosphates and even less for the polynucleotides. In the 2'-chloro-2'-deoxyuridine series the O2, 2'-cyclonucleoside was formed in addition to the arabinonucleoside.
