title: Polynucleotides. XXIV. Synthesis and properties of a dinucleoside monophosphate derived from uridine 6,2-cyclonucleoside.
abstract: A dinucleoside monophosphate, 6,2'-anhydro-6-oxy-1-beta-D-arabinofuranosyluracil-phosphoryl- (3'-5')-6,2'-anhydro-6-oxy-1-beta-D-arabinofuranosyluracil (I) was synthesized by the condensation reaction using DCC from 5'-monomethoxytrityl derivative(VII) and 3'-acetyl-5'-phosphate(X) of the monomer units. Yield was ca. 70%. UV of compound I showed no hypochromicity and its CD spectrum showed only a trough at 252 nm. No temperature dependency of epsilon and [Q] values was observed. These results suggested an unstacked random conformation for I. Complex formation of I with cycloadenosine oligomer could not be detected under the experimental condition.
