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.
为三乙酰基的不对称合成的高效的协议d -赤-sphingosine和d-1-deoxyallonojirimycin已经开发从可商购的炔丙醇开始。关键步骤涉及Sharpless不对称环氧化和2,3-环氧醇的Miyashita C2选择性内模叠氮化物打开。
