  摘要：

  基于哌啶的竹本催化剂已成功用于活化异吲哚啉酮的新型不对称转移羟甲基化，使我们能够以良好至优异的产率（48-96%）和对映体纯度（81:19-97:3 er）制备对映体富集的羟甲基化加合物。 ）。为了在不影响选择性的情况下提高反应速率，采用了仔细优化的甲醛替代物，提供了具有碱触发释放的无水甲醛的便捷来源。底物范围包括 34 个条目，显示了不对称转化的相当普遍性，大多数条目在 24-48 小时内表现出完全转化。还进行了放大实验和多个对映选择性下游转化，表明了产品的预期合成效用。

  Utilizing a chiral bicyclic imidazole organocatalyst and adopting a continuous injection process, an alternative route has been developed for the efficient synthesis of chiral phthalidyl ester prodrugs via dynamic kinetic resolution of 3‐hydroxyphthalides through enantioselective acylation (up to 99 % ee). The computational studies suggest a general base catalytic mechanism differing from the widely
