An efficient process is described for the totalsynthesis of the alkaloid (-)-codonopsinine. The synthetic strategy is based on the diastereoselective hydrocyanation of a 2,3-dialkoxyaldehyde derived from L-threonine followed by a reductive alkylation of the nitrile function with a Grignard compound and sodiumborohydride. The resulting aminotriol was then cyclized into the target molecule after selective
