Cinchonidine is a cinchona alkaloid, which belongs to the orthorhombic crystal system and P212121 space group.

Application

The enantioselective hydrogenation of ethyl pyruvate in the presence of cinchonidine modified platinum/alumina catalyst leads to the enantiomeric excess of ethyl (R)-lactate.
