A general way for the functionalization of ribonucleosides is described. The method involves the synthesis of the methyl-ribofuranoside derivative 6 equipped with a linker at the 2-hydroxy group (Scheme 2). After introduction of the nucleic-acid bases under standard conditions (Scheme 3), the resulting β-D-ribonucleosides 8 and 10 are further transformed to derivatives with lipophilic, intercalating
