A stereospecific synthesis of L-deoxyribose, L-ribose and L-ribosides

Using an inexpensive D-galactose from the chiral pool, L-deoxyribose, L-ribose and their derivatives were synthesized via mild reaction conditions. During the synthesis of L-deoxyribose, the key deoxygenation of the 2-hydroxy group of 3,5-O-dibenzyl-methyl-L-arabinofuranoside was performed by reduction of the corresponding triflate with tetrabutylammonium borohydride in high yield. During the synthesis of L-ribose, the key step of inversion of the 2-hydroxy group in the same substrate was carried out by intramolecular SN2 tandem reaction. Then the L-ribosyl donors were submitted to glycosidations according to Vorbrüggen's conditions to give L-ribosides (L-uridine, L-5-fluorouridine, L-iodouridine, L-thymidine, L-puridine, L-adenosine and L-guanosine) in excellent yields.
