Abstract
(Salen)manganese(III) complex 5 [2,2′-[2-methylpropane-1,2-diylbis (nitrilomethylidyne)]-5,5′ - dimethyl-6,6′ - (1-phenylpropyl)diphenolatomanganese (III)] bearing one set of stereogenic centers in the 1-phenylpropyl substituents and a geminally dimethylated ethylenediamine moiety was found to catalyze the enantioselective epoxidation of E olefins just as effectively as the reported (salen)manganese(III) complex 2, which bears two sets of stereogenic centers, in the ring substituents and on the ethylenediamine moiety.Keywords
