On the timing of hydrolysis / reoxidation in the osmium-catalyzed asymmetric dihydroxylation of olefins using potassium ferricyanide as the reoxidant

Abstract

Hydrolysis is shown to precede reoxidation in the catalytic cycle for the asymmetric dihydroxylation of olefins using potassium ferricyanide as the stoichiometric reoxidant, thereby accounting for the observed absence of a non-enantioselective “second cycle.”

    Alkaloids are a group of natural products that contain mostly basic nitrogen atoms. This group also includes some related compounds with neutral and even weakly acidic properties.23 Alkaloids are plant metabolites that have a nitrogen-containing ring structure, alkali-like chemical reactivity, and most of them show biological activities.24
