Pseudo-enantiomeric carbohydrate-based N-heterocyclic carbenes as promising chiral ligands for enantiotopic discrimination

Org. Biomol. Chem., 2020, 18,3012-3016
DOI: 10.1039/D0OB00155D, Communication
Alexander S. Henderson, John F. Bower, M. Carmen Galan
The practical synthesis of pseudo-enantiomeric carbohydrate-based NHC–Rh complexes bearing C1 or C3 sterically differentiated positions is reported. We show that steric bulk at either C1 or C3 leads to enantiotopic discrimination in the hydrosilylation of acetophenone.
