Abstract :
New, sterically hindered chiral salen–Mn(III) complexes, 5 and 6, were prepared from an aldehyde derived from BINOL. These substances catalyze efficient, enantioselective NaOCl-promoted epoxidations of olefins and enantioselectivities as high as 96–99% ee are observed in epoxidations of cis-β-methylstyrene and 2,2-dimethylchromene.
