Sintesi di polimeri funzionali per la catalisi asimmetrica

In recent years, the asymmetric organocatalysis has been recognized as an independent area of synthetic chemistry, where the goal is the preparation of any chiral molecule in an efficient, rapid, and stereoselective manner. In this context we have synthesized macromolecular catalysts soluble in the reaction conditions and that can finally recovered by simple precipitation and subsequent filtration. In particular different active compounds (9-epi-NH2 hyidroquinine and β –isocupreidine) have been linked to the terminal group of the main chain polyethylene glycol monomethyl ether (PEG-5000). The macromolecular catalysts have been tested in different reactions and the results have been compared with those of the correspondent low molecular compounds.
