Recoverable PEG-supported copper catalyst for highly stereocontrolled nitroaldol condensation.


PMID 17480085

Abstract

A new poly(ethylene glycol)-modified DAT2-Cu(OAc)2 complex smoothly catalyzes a base-free nitroaldol condensation in a highly enantioselective manner (ee up to 93%) also in reagent-grade solvent and in the presence of air. Effective recovery and recycling (up to five runs) of supported catalysts are documented.
