The stereoselectivity of both the Wittig and the Homer-Wadsworth-Emmons reactions allows for the synthesis of orthogonally protected fumarates and maleates, respectively, from α-keto esters. This methodology has been shown to be useful in the synthesis of a derivative of the pH sensitive cis-aconitic linker, important for prodrug approaches in drug delivery. We have incorporated this linker into a
Wittig 和 Homer-Wadsworth-Emmons 反应的立体选择性允许分别从 α-酮酯合成正交保护的富马酸酯和马来酸酯。该方法已被证明可用于合成 pH 敏感的顺式乌头接头的衍生物,这对于药物递送中的前药方法很重要。我们已将此接头纳入基于胆固醇的 PEG 化脂质中,以用于脂质体药物和基因传递中的潜在用途。使用 HPLC 分析也显示合成的脂质是 pH 可降解的。
