Chem Commun (Camb). 2024 Jan 16;60(6):678-681. doi: 10.1039/d3cc05447k.

Abstract

The first atroposelective Chan-Lam coupling for the synthesis of C-N axial enantiomers is reported with good yields and ee. MnO2 additive is crucial for the success of the coupling. The longstanding problem of the lack of enantioselective synthesis to make chiral C-N linked atropisomers is solved.
