In view of biological activities of both 1,3-dioxolanyl nucleosides and C-nucleosides, d- and l-1,3-dioxolanyl C-nucleosides have been synthesized as potential antiviral and/or anticancer agents. Asymmetric synthesis of four new optically pure d- and l-1,3-dioxolanyl triazole C-nucleosides has been accomplished via key intermediate 5a and 5b starting from d- and l-2,3-O-isopropylidene glyceraldehyde
