    Abstract: An optically active compound production method using a column reactor, a column for column reactor is charged with asymmetric catalyst particles to produce the column reactor, and reaction compound is introduced into column reactor to bring reaction compound into contact with asymmetric catalyst particles, whereby reaction compound is converted to optically active compound. Asymmetric catalyst particles are preferably resin particles that are prepared from a monomer composition containing a proline derivative monomer having unsaturated bond and radical polymerization initiator and serve as catalyst for enamine mechanism reaction. Asymmetric catalyst particles are preferably resin particles prepared by micro-channel method including injecting monomer composition into continuous phase to thereby form droplets of monomer composition in continuous phase and then heating droplets to cause proline derivative monomer having an unsaturated bond to undergo radical polymerization.
