2-Deoxy-L-ribose   2-Deoxy-L-Ribose is the key intermediate in the synthesis of L-nucleosides. Recently, L-nucleosides are attracting attention as antiviral agents. Some L-nucleosides such as L-thymidine, L-2'-thiacytidine (3TC) and L-2’,3’-dideoxycytidine (L-ddC) are much less toxic and have better antiviral activity than their D-isomers.
