synthesis of γ-lactones through the merger of Umpolung catalysis with a ketoreductase-catalyzed dynamic kinetic resolution, reduction, and cyclization. This combined approach delivers highly enantio- and diastereoenriched heterocycles and demonstrates the feasibility of integrating NHC catalysis with enzymatic processes.

化学酶流形下结合
生物和小分子催化剂为合成界带来了一系列显着的优势。我们在此报告了通过将 Umpolung 催化与酮还原酶催化的动态动力学拆分、还原和环化相结合,成功开发了 γ-内酯的两步/单瓶合成。这种组合方法可产生高度对映体和非对映体富集的杂环,并证明了将 NHC 催化与酶促过程相结合的可行性。
