The mildness and low basicity of vinylzinc species functioning as a nucleophile in addition to alpha-chiral aldehydes is characterized by lack of epimerization of the vulnerable stereogenic center. This is demonstrated by a highly diastereoselective synthesis of 1-deoxygalactonojirimycin in eight steps from commercial starting materials with overall yield of 35%.

configurational 1-deoxynojirimycin isomers have been synthesized starting from a chiral cyanohydrin as the common precursor. The cyanohydrin chiral pool building block is easily accessible in large quantities by using almond hydroxynitrile lyase as the chiral catalyst in condensing hydrogen cyanide and crotonaldehyde. Our work complements the large body of literature on the synthesis of 1-deoxynojirimycin derivatives
