Stereochemically Defined Osmium Centers from Asymmetric Diamination of Olefins:Mechanistic Implications for Osmium-Mediated Acrylate Functionalization

摘要

Investigations on transition-metal complexes with stereogenic metal centers were pioneered by Brunner in 1969,who achieved the resolution of a complex with a pseudo-tetrahedrally coordinated chiral maangenese atom.~([1]) Such complexes,which are also referred to as "chiral-at-metal complexes",~([2]) have gained important application in organic synthesis,~([3]) chiral recognition,~([4]) material sciences,~([5]) and fundamental basic research.~([6])
