What is Cinchonidine?

Description

Cinchonidine is an alkaloid found in the bark of most varieties of cinchona shrubs. It and its stereoisomer cinchonine have long been used to direct chirality in the synthesis of asymmetric organic compounds.?More recently, Dutch chemists created chiral metals by crystallizing their salts in the presence of cinchonidine.

Chemical properties

white to light yellow crystal powde

The Uses of Cinchonidine

Cinchonidine occurs in most varieties of Cinchona bark and is stereoisomeric with Cinchonine. Cinchonidine exhibits Antimalarial properties.

The Uses of Cinchonidine

antiamebic, antiprotozoal

Definition

ChEBI: 8-epi-Cinchonan in which a hydrogen at position 9 is substituted by hydroxy (R configuration). A diasteroisomer of cinchonine, it occurs in the bark of most varieties of Cinchona shrubs, and is frequently used for directing chirality in asymmetric synthesis.

Flammability and Explosibility

Non flammable

Purification Methods

Crystallise cinchonidine from aqueous EtOH. For the N-benzylcinchonidinium chloride see above entry in this section. [Beilstein 23 III/IV 2824.]
