NHC-catalyzed enantioselective synthesis of β-trifluoromethyl-β-hydroxyamides
MetadataShow full item record
The N-heterocyclic carbene (NHC) catalyzed formal [2+2] cycloaddition between α-aroyloxyaldehydes and trifluoroacetophenones, followed by ring-opening with an amine or reducing agent is described. The resulting β-hydroxy-β-trifluoromethyl amide and alcohol products are produced with reasonable diastereocontrol (typically ~70:30 dr) and excellent enantioselectivity, and can be isolated in moderate to good yield as a single diastereoisomer.
