of the tetrasaccharide subunit in the proposed structure of durantanin I is reported. The signature step is represented by the unique assembly of apiofuranoside ring by the sequential PdRu metal catalysis. Per‐dihydroxylation at the late stage delivered the target compound in a highly efficient manner. In addition, a tetrasaccharide derivative possessing unnatural apiose unit was also synthesized
据报道,在杜兰丹宁I的拟议结构中四糖亚基的收敛合成。签名步骤通过由连续的Pd apiofuranoside环的独特组件表示 Ru金属催化。在后期进行过二羟基化反应以高效的方式提供了目标化合物。另外,还以与天然形式相当的效率合成了具有非天然apiose单元的四糖衍生物。
