Synthesis of differently protected 1-C-methyl-ribofuranoses intermediates for the preparation of biologically active 1 '-C-methyl-ribonucleosides

Starting from D-ribose, differently protected 1-C-methyl-D-ribofuranoses have been prepared as intermediates for the synthesis of variously modified 1'-C-methyl-ribonucleosides, a class of compounds potentially endowed with interesting biological activity.
