Numerous biologically active natural products contain furanoses and pyranoses with mono- and dihydroxylated substituents. However, much of the structure−activity studies on such molecules is gathered on the aglycons without attention to the corresponding carbohydrate components. Consequently, there are few synthetic procedures that enable the rapid preparation of mono- and dihydroxyfuranoses and mono-
许多具有生物活性的天然产物都含有呋喃糖酶和带有单羟基和二羟基取代基的吡喃糖酶。但是,对此类分子的许多结构活性研究都是在糖苷配基上进行的,而没有关注相应的碳水化合物成分。因此,几乎没有能够快速制备单和二羟基呋喃糖酶和单和二羟基吡喃糖的合成方法,也没有关于3,4-二羟基氧戊糖的报道。在本文中,我们报告了正交保护的五元,六元和七元碳水化合物衍生物的实用合成。合成这些分子的简洁方式允许快速制备类似物,旨在发现吡喃糖骨架上的环大小和单个羟基部分的作用。
