title: Stereocontrolled synthesis of oligodeoxyribonucleoside boranophosphates via stereodefined H-phosphonate intermediates.
abstract: P-Stereodefined oligodeoxyribonucleoside boranophosphates (PB-ODNs) were successfully synthesized by the conversion of diastereopure H-phosphonate intermediates. Thermal denaturation studies clearly showed that the duplex stability of PB-ODNs with the complementary DNA and RNA depends on the stereochemistry of the boranophosphate linkages.
