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-epoxy alcohol.

An efficient and versatile method for the stereospecific construction of α,ω-cis- and α,ω-trans-disubstituted oxepane skeletons is described. Cyclization of the hydroxy epoxides promoted by a (Bu3Sn)2O/ Zn(OTf)2 system proceeded via an S(N)2 process and exo mode selectivity regardless of the configuration of the hydroxyl and the epoxy groups to provide the corresponding oxepanes in excellent yields.
