We report the ready asymmetric synthesis of nucleoside analogues containing a 1,3-dithiolane ring that mimics the sugar moiety of natural nucleosides. The synthesis is accomplished in three main steps from benzoyloxyethanal 1,3-dithiolane, the key step being its conversion into a chiral monosulfoxide by a modified Sharpless sulfo-oxygenation reaction. The nucleoside analogues were obtained in good
我们报告了包含 1,3-二硫戊环的核苷类似物的不对称合成,该环模拟天然核苷的糖部分。苯甲酰氧基乙醛 1,3-二硫戊环的合成通过三个主要步骤完成,关键步骤是通过改良的 Sharpless 磺基氧化反应将其转化为手性单亚砜。以良好的总产率和优异的对映体过量获得了核苷类似物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
