4-AMINO-3-(2,3,5-TRI-O-BENZYL-β-D-RIBOFURANOSYL)-5-PYRAZOLECARBONITRILE. SYNTHESIS AND CONVERSION INTO A SUGAR-BLOCKED 5,7-DISUBSTITUTED FORMYCIN ANALOG

Article abstract of DOI:10.1016/0008-6215(88)84056-4

The title compound, a potential intermediate to protected C-nucleoside analogs related to formycin A, was synthesized via a new route wherein 2,3,5-tri-O-benzyl-1-O-(p-nitrophenyl)-D-ribofuranose was converted to 2,5-anhydro-3,4,6-tri-O-benzyl-D-allonic a
