enantioselective epoxide ring opening with hydrofluorinating agents mediated by chiral non-racemic Lewis acids is reported. The reaction of cyclohexene oxide (1) with KHF2/18-crown-6 is trans-diastereoselective and proceeds with 55% ee to form (R,R)-(−)-2-fluorocyclohexanol (2) in the presence of Jacobsen’s (S,S)-(+)-(salen)chromium chloridecomplex A. From racemic epoxides such as styrene oxide (9) or phenyl
Enantiomeric recognition of organic ammonium salts by chiral dialkyl-, dialkenyl-, and tetramethyl-substituted pyridino-18-crown-6 and tetramethyl-substituted bispyridino-18-crown-6 ligands: comparison of temperature-dependent proton NMR and empirical force field techniques
