Diastereoselective and regioselective [1,5]-C,H insertion reactions of 2'-deoxy-3'-diazomalonate nucleosides afforded τ-butyrolactones of nucleosides as chiral synthons for the preparation of 2'-C-branched nucleosides.

An effective method for the preparation of 8-membered ring enone 1 in sufficient quantities was developed. First, optically active trialkoxyaldehyde 3 was prepared by diastereoselective dihydroxylation of olefin 7 derived from D-pantolactone. Secondly, 8-
