Introduction of
Cinchonidine
:
Cinchonidine is an alkaloid found in the cinchona tree and the vine. It is used in asymmetric synthesis in organic chemistry. It is a stereoisomer and pseudoenantiomer of cinchonine.
Function of
Cinchonidine
:
Cinchonidine
is 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. It has a
role
as a metabolite.
