Recoverable PEG-Supported Copper Catalyst for Highly Stereocontrolled Nitroaldol Condensation
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...

Zusammenfassung: | 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. |
