摘要

Abstract:(2S, 4R)-4-Hydroxyproline has been anchored to the monomethyl ether of poly (ethylene glycol), MW 5000, by means of a succinate spacer to afford a soluble, polymer- supported catalyst (PEG-Pro) for enantioselective aldol and iminoaldol condensation reactions. This organic catalyst can be considered as a minimalistic version of a typeI aldolase enzyme, with the polymer chain replacing the enzyme◊ s peptide backbone, and ...
