Asymmetric oxohydroxylation of α-alkyl enoates with potassium permanganate catalyzed by monocationic quaternary...
Buchler Glossary
The Sharpless Aminohydroxylation allows the syn-selective preparation of 1,2-amino alcohols by reaction of alkenes with salts of N-halosulfonamides, -amides and -carbamates using OsO4 as a catalyst. Enantioselectivity is achieved through the addition of Dihydroquinine– and Dihydroquinidine-derived chiral ligands.
Please find some examples of Aminohydroxylation promoted by Cinchona Alkaloids in our Buchler Chiral Catalyst Search.
