Asymmetric dihydroxylation of alkenes with osmium tetroxide: chiral N,N′-dialkyl-2,2′-bipyrrolidine complex
Abstract
Asymmetric osmylation of alkenes by using N,N′-dialkyl-2,2′-bipyrrolidines as the chiral ligands shows a high asymmetric induction and a marked dependence of the enantioselectivity on both the N-alkyl group and the reaction solvent.
