摘要：

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-beta -methylstyrene and 2,2-dimethylchromene.
