General description

Hydroquinine is a cinchona alkaloid.

Application

Hydroquinine may be used in the preparation of its derivatives such as C9 epihydroquinine, 9-acetoxy-10,11-dihydroquinine and 10,11-dihydroquinine monohydrochloride. It may also be used as a catalyst for the methylhydrazine promoted asymmetric α-hydroxylation of β-keto esters in the presence of molecular oxygen as oxidant to form enantioenriched α-hydroxy β-dicarbonyl compounds.
