General description

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.

Mechanism and the origin of enantioselectivity in the decarboxylative protonation of α-amino malonate hemiester promoted by epicinchona-thiourea hybrid organocatalyst is established by using the DFT(M06-2X/6-311+G**//ONIOM2) computational methods. The origin of stereoselectivity rendered by this hybrid bifunctional catalyst in asymmetric protonation...

The preparation of stable metal nanoparticles requires a strong interaction between the (organic) stabilizer and the metal surface that might alter the catalytic properties. This behavior has been described as "poisoning" since the stabilizer normally decreases the catalytic activity due...
