way to KDO, we developed a new strategy based on an aqueous hetero Diels-Alder reaction with a water-soluble diene derived from D-glyceraldehyde, followed by a dihydroxylation of the newly created double bond. The stereoselectivities of these reactions were investigated to give rise to 2-deoxy-KDO, which was sulfenylated via the enolate to yield β-thioglycoside, the hydrolysis of which led to KDO.
为了在合成KDO的过程中利用合成中间体的优势,我们开发了一种新的策略,该策略基于含水杂Diels-Alder反应与衍生自D-甘油醛的水溶性二烯的反应,然后对新创建的双键进行二羟基化。研究了这些反应的立体选择性以产生2-脱氧-KDO,其通过烯醇盐被亚硫基化以产生β-硫代糖苷,其水解导致KDO。
