title: Synthesis and properties of spiro nucleosides containing the barbituric acid moiety.
abstract: The two chiral spiro nucleosides 4 and 5 containing the barbituric acid moiety were efficiently synthesized from optically pure precursors, and their properties were studied. The carbocyclic nucleoside 5 is considerably more stable against ring opening than the deoxyribosyl derivative 4. Both compounds present enhanced hydrogen bonding capacity with diacetyladenosine.
