A new boranophosphorylation reaction for the synthesis of deoxyribonucleoside boranophosphates

Deoxyribonucloside 3′-boranophosphate derivatives including adenine, cytosine, guanine, and thymine bases were synthesized in good yields by the use of a new boranophosphorylating reagent. The reaction was successfully applied to the formation of internucleotidic boranophosphate linkages.
