Efficient Polymer-Supported Sharpless Alkene Epoxidation Catalyst

Efficient Polymer-Supported Sharpless Alkene Epoxidation Catalyst

Homogeneous linear poly(tartrate ester) ligands provide high chemical yields and enantiomeric excesses in the epoxidation of trans-hex-2-en-1-ol using Ti(OPri)4-tert-butyl hydroperoxide. Branched poly(tartrate ester) can be use as heterogeneous ligands in the epoxidation of trans-hex-2-en-1-ol using...

Zusammenfassung:Homogeneous linear poly(tartrate ester) ligands provide high chemical yields and enantiomeric excesses in the epoxidation of trans-hex-2-en-1-ol using Ti(OPri)4-tert-butyl hydroperoxide. Branched poly(tartrate ester) can be use as heterogeneous ligands in the epoxidation of trans-hex-2-en-1-ol using Ti(OPri)4-tert-butyl hydroperoxide. Removal and recovery of the polymer catalyst is a simple filtration at the end of reactions.
