A general approach to the stereoselective synthesis of 5a-carbasugars has been developed. The route mimics our palladium-catalyzed glycosylation/postglycosylation approach to carbohydrates in that it also utilizes a highly regio- and stereospecific palladium-catalyzed allylation and postglycosylation reaction sequence for the installation of either D- or L-cyclitols. This cyclitolization/postcyclitolization sequence was used for the enantioselective synthesis of a cyclitol analogue of SL0101, its D-sugar enantiomer, as well as several acetylation pattern analogues.
已开发出一种 5a-碳环糖立体选择性合成的通用方法。该路线模仿了我们使用钯催化糖基化/后糖基化方法合成碳水化合物的方法,因为它还利用了高度区域和立体特异性的钯催化烯丙基化和后糖基化反应序列,用于安装 D-或 L-环糖醇。该环化/后环化序列用于 SL0101 的环糖醇类似物、其 D-糖对映异构体以及几种乙酰化模式类似物的对映选择性合成。
