Efficient and β-stereoselective synthesis of pyrazole C-nucleosides

3(5)-(β-D-Ribofuranosyl)pyrazole 1 and 3(5)-(2-deoxy-β-D- ribofuranosyl)pyrazole (2) were stereoselectively synthesized by cyclization of 1,2-diazafulvene intermediates obtained from 2,3,5-tri-O-benzyl-D-ribose (5) and 3,5-di-O-benzyl-2-deoxy-D-ribose (10
