Jørgensen–Hayashi catalysts supported on poly(ethylene glycol)s as highly efficient and reusable organocatalysts for the enamine-catalyzed asymmetric Michael reaction
Organic & Biomolecular Chemistry(2015)
摘要
A new kind of recyclable and reusable PEG-supported Jorgensen-Hayashi catalyst is synthesized for the first time and proven to be efficient for the enamine-catalyzed asymmetric Michael reaction with generally moderate to good diastereoselectivity and high to excellent enantioselectivity (up to 6 : 1 dr, 99% ee). The prepared PEG-supported catalyst can be recovered eight times and was found to provide similar diastereoselectivity and enantioselectivity to unsupported functional catalysts.
