An immobilized chiral bifunctional iminophosphorane superbase organocatalyst has been developed and applied in a range of challenging enantioselective reactions. A unique feature of this novel catalytic system is that the final step creation of the iminophosphorane occurs at the point of immobilization. The utility of the immobilized catalyst system was demonstrated in the nitro-Mannich reaction of ketimines as well as the conjugate addition of high pKa 1,3-dicarbonyl pro-nucleophiles to nitrostyrene. Catalyst recycling was also demonstrated.

A unique approach to the synthesis of mono and disubstituted γ-pyrones from acylated Meldrum's acid and vinyl ethers has been developed. The convenient one pot synthesis of these versatile polyketide equivalents is accomplished without strong base or low temperature.
