General Method for the Synthesis of 2'-Azido-2',3'-dideoxynucleosides by the Use of -Hydride Shift and &β-Elimination Reactions

The title nucleoside (16U, C, G and H) were synthesized from pyrimidine and purine ribonucleosides in about 30percent overall yield in 6 steps via key intermediates, protected 3'-deoxy-arabino-nucleosides, which were obtained by deoxygenative -hydrid
