approach toward the synthesis of 4,5-disubstituted oxazolidin-2-one scaffolds. The developed approach is based on a combination of an asymmetric aldol and a modified Curtius protocol, which uses an effective intramolecular ring closure to rapidly access a range of oxazolidin-2-one building blocks. This strategy also permits a straightforward and concise asymmetric total synthesis of (−)-cytoxazone. Consisting
在本文中,我们报告了一种有效的合成4,5-二取代的恶唑烷-2-酮骨架的方法。所开发的方法基于不对称羟醛和改进的Curtius方案的组合,该方案使用有效的分子内环闭合来快速进入一系列恶唑烷-2-酮结构单元。该策略还允许(-)-cytoxazone的直接和简洁的不对称总合成。由三个步骤组成,这是迄今为止报道的最短的合成方法之一。最终,这个方便的平台将为药物发现的早期阶段提供有希望的方法。
