General description

(+)-Cinchonine, one of the alkaloids found in the barks of cinchona tree, is mainly used in the treatment of malaria. It belongs to the monoclinic crystal system and P21 space group. The solubility of cinchonine can be improved by the formation of inclusion complexes with cyclodextrins.

Application

(+)-Cinchonine, in the presence of lithium diisopropylamide (LDA) forms a complex, which can catalyze the asymmetric conjugate addition of benzyl- and alkylphosphonates to aromatic and heteroaromatic nitroalkenes to form the corresponding adducts.
