the literature for the asymmetric synthesis of (R)-paraconyl alcohol. Herein, we report the first organocatalytic approach for the short asymmetric synthesis of (R)-paraconyl alcohol in four steps and by a single column purification. Asymmetric syntheses of IM-2, SCB2, and A-factor γ-butyrolactone autoregulators were achieved from (R)-paraconyl alcohol in three steps.
发现(R)-花生四烯醇是许多γ-丁内酯自动调节剂合成的关键中间体。迄今为止,手性辅助方法和酶促拆分是文献中用于不对称合成(R)-对二甲苯基醇的两种常用策略。在本文中,我们报告了第一种有机催化方法,该方法可通过四个步骤并通过单柱纯化进行短时间的不对称合成(R)-对苯二酚。由(R)-对二甲苯醇分三步完成IM-2,SCB2和A因子γ-丁内酯自动调节剂的不对称合成。
