on amino acid and β-ketophosphonate chemistry, as well as employment of internal asymmetric induction for the creation of the new chiral centers proved successful. With proper choice of reaction conditions, the approach can also be applied in selective preparation of several isomers of deoxycastanospermine. The length (9 steps) and overall yield of the title compound trihydroxyindolidine 1, 7.3%, compares
基于氨基酸和β-酮膦酸酯化学,开发了一种新的有效的对映选择性全合成标题脱氧卡那精胺衍生物,并证明内部不对称诱导用于创建新的手性中心是成功的。随着反应条件的适当选择,该方法也可以在deoxycastanospermine的多种异构体的选择性制备施用。标题化合物三羟基吲哚啶1的长度(9步)和总产率为7.3%,与相似化合物的文献合成相比较。
