title: Synthesis of novel nucleosides.
abstract: A new spironucleoside structural type and two new bicyclic nucleoside structural types were synthesized from the reaction of ribose nitrile oxide with dimethyl acetylenedicarboxylate. Next, a synthetic method for novel meso-ionic nucleoside structual type is presented.
