General description

Cinchonine is a cinchona alkaloid generally found in the bark of Cinchona officinalis plants. It is a pseudoenantiomer that is commonly employed in malaria therapy. Cinchonine is also used as an organocatalyst in many asymmetric reactions.

Application

Cinchonine can be used:
  • As a substrate in the study of supercritical fluid chromatography (SFC) parameters in pharmaceutical analysis.
  • To prepare possible butyrylcholinesterase inhibitors.

This paper describes the synthesis and anticholinesterase potency of Cinchona-based alkaloids; ten quaternary derivatives of cinchonines and their corresponding pseudo-enantiomeric cinchonidines. The quaternization of quinuclidine moiety of each compound was carried out with groups diverse in their size: methyl, benzyl

An asymmetric conjugate addition of 3-monosubstituted oxindoles to a range of (E)-1,4-diaryl-2-buten-1,4-diones, catalyzed by commercially available cinchonine, is described. This organocatalytic asymmetric reaction affords a broad range of 3,3'-disubstituted oxindoles that contain a 1,4-dicarbonyl moiety and vicinal quaternary and tertiary
