Pickering interfacial catalysts for asymmetric organocatalysis

A catalytically active Pickering emulsion was established for asymmetric aldol reaction. Both high reactivity and high selectivity were achieved on the emulsion interface via tailoring the hydrophobicity of the proline-functionalized nanoparticles.

Efficient synthesis of zirconium poly(styrene-phenylvinylphosphonate)phosphate-supported proline as a recyclable catalyst for direct asymmetric aldol reactions in water

A completely non-chromatographic and highly large-scale adaptable synthesis of zirconium poly(styrene-phenylvinylphosphonate)phosphate-supported l-proline (ZrPS-PVPA-Pr) has been developed in only three steps overall.

Synthesis and properties of novel helical 3-vinylpyridine polymers containing proline moieties for asymmetric aldol reaction

Novel helical vinyl polymers bearing l/d-proline amide moieties were prepared to catalyze asymmetric aldol reactions, which afforded faster reaction rate but slightly poorer enantio-selectivity than the low molar mass counterparts.

Design and application of the recyclable poly(l-proline-co-piperidine) catalyst for the synthesis of mesityl oxide from acetone

A novel bi-component poly(l-proline-co-piperidine) catalyst was developed for the synthesis of mesityl oxide from acetone. The catalyst is more eco-friendly than traditional inorganic bases, avoiding the generation of corrosive solid, and the catalytic mechanism was studied.
