应用
3-Buten-2-one can undergo conjugate addition with methanol over the solid base catalysts to afford 4-methoxy-butan-2-one. It can also undergo coupling reaction with alkyltins and alkynes in the presence of a nickel complex to form stereo-defined conjugated enynes.

Non-interpenetrating star polymer catalysts designed to mimic the site isolation characteristics of enzymes enable the one-pot combination of multiple otherwise incompatible catalysts for asymmetric cascade reactions that involve iminium, enamine, and H-bonding catalysis. Control experiments replacing star polymer catalysts with
