Novel chitosan‐supported cinchona alkaloids have been developed as heterogeneous catalysts for enantioselective Michael reaction . As‐synthesized products as organocatalysts for asymmetric Michael reaction have a high efficiency, providing highly functionalized products (containing adjacent quaternary and tertiary stereocenters) with good stereoselectivity (up to 93% enantiomeric excess) in high yields and recyclability (up to five runs).
