Abstract

In situ generated osmium-diamine chelates from 2,3-diaminopropionic acid or diaminosuccinic acid represent efficient catalysts for the highly productive aminohydroxylation of alkenes. The reaction can be employed with various osmium salts and successful catalyst recycling was demonstrated for a representative example. The catalyst design derives from the general structural features of recently investigated osmium complexes from alkene diamination reactions. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
