  Expedient Synthesis of Chiral Oxazolidinone Scaffolds via Rhodium-Catalyzed Asymmetric Ring-Opening with Sodium Cyanate

  摘要：

  A method for synthesizing chiral oxazolidinone scaffolds from readily available oxabicyclic alkenes is described. The reaction utilizes a domino sequence of Rh(I)-catalyzed asymmetric ring-opening (ARO) with sodium cyanate as a novel nucleophile followed by intramolecular cyclization to generate oxazolidinone products in excellent enantioselectivities (trans stereochemistry).
