自D-阿拉伯糖经以下五步反应合成了2,3-内醚-5-去羟-α-D-来苏糖甲基甙 (Ⅵ):D-阿拉伯糖(Ⅰ)→D-阿拉伯糖甲基呋喃甙(Ⅱ,α-和β-端基差向异构体混合物)→2,3,5-三-O-对甲苯磺酰基-α-D-阿拉伯糖甲基呋喃甙(Ⅲ)→2,3-二-O-对甲苯磺酰基-5-去羟-5-碘代-α-D-阿拉伯糖甲基呋喃甙(Ⅳ)→2,3-二-O-对甲苯磺酰基-5-去羟-α-阿拉伯糖甲基甙(Ⅴ)→2,3-内醚-5-去羟-α-D-来苏糖甲基甙(Ⅵ)。最后产物(内醚糖)的结构是根据第三报中所提出的证据肯定的。

Byt the same route outlined in Part Ⅲ of this series[1], the title compound was prepared from D-arabinose by five stages of reactions.
