英文摘要Solid acid-chiral amine hybrids have been synthesized and explored as recyclable and reusable enamine-type asymmetric catalysts. Simple chiral amine-polyoxometalate (CA-POM) hybrids were identified as the optimal catalysts to promote a range of enamine-based transformations with high activity and excellent stereoselectivity under either neat or aqueous conditions. A catalyst loading as low as 0.33 mol-% (1 mol-% loading of chiral amine) was sufficient to achieve fast reactions and high stereoselectivities. Under both conditions, the CA-POM hybrid catalysts could be easily recycled and reused up to seven times with essentially unchanged stereoselectivity, although diminished activity was observed upon extensive reuse, especially under aqueous conditions.
