Chiral bis(oxazolinyl)phenylrhodium(III) complexes as Lewis acid catalysts for enantioselective allylation of aldehydes
Abstract
The reaction of (Phebox)SnMe3 1 [PheboxH = 2,6-bis(oxazolinyl)benzene] and [(c-octene)RhCl]2 in the presence of CCl4 provided air-stable and water-tolerant (Phebox)RhCl2(H2O) complexes 2 which acted as asymmetric catalysts for the enantioselective allylation of aldehydes in up to 80% ee.
