title: Stereocontrolled synthesis of dinucleoside boranophosphates by an oxazaphospholidine method.
abstract: Stereodefined dinucleoside boranophosphates were synthesized from diastereopure nucleoside 3'-oxazaphospholidine derivatives. The new method is based on the stereospecific formation of dinucleoside phosphite intermediates catalyzed by a non-nucleophilic acidic activator, N-(cyanomethyl)pyrrolidinium triflate, and the boronation of the intermediates.
