An efficient and economical approach to the synthesis of antitumor and anti-inflammatory surinamensinol B (1) and antimalarial polysphorin analogue 2 has been achieved with high enantiomeric purity (96 % ee) by starting from commercially available 3,4,5-trimethoxybenzaldehyde. The key steps of the strategy include a Co-catalyzed two-stereocentered hydrolytic kinetic resolution (HKR) of racemic 2-[(methoxymethoxy)(3
通过从市售的 3,4,5-三甲氧基苯甲醛开始,以高对映体纯度 (96% ee) 实现了一种高效且经济的合成抗肿瘤和抗炎 surinamensinol B (1) 和抗疟疾 polysphorin 类似物 2 的方法。该策略的关键步骤包括外消旋 2-[(甲氧基甲氧基)(3,4,5-三甲氧基苯基)甲基]环氧乙烷 (13) 的共催化双立体中心水解动力学拆分 (HKR) 作为手性诱导步骤,然后是三信反应。手性环氧化物 14 和手性二醇 15 用于两种化合物的合成。
