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.
在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。
