title: Hydrolysis in 2'-chloro-2'-deoxy nucleosides, -nucleotides and -polynucleotides to arabinose-derivatives.
abstract: 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 the 2'-chloro-2'-deoxyuridine series the O2, 2'-cyclonucleoside was formed in addition to the arabinonucleoside.
