An efficient protocol for the asymmetric synthesis of triacetyl-d-erythro-sphingosine and D-1-deoxyallonojirimycin has been developed starting from commercially available propargyl alcohol. The key steps involved Sharpless asymmetric epoxidation and Miyashita C2 selective endo-mode azide opening of the 2,3-epoxyalcohol.
