Abstract

不對稱有機催化 不對稱加成反應
This thesis dealt with the synthesis and application of novel prolinamide-camphor organocatalysts that derived from the coupling of trans-4-hydroxy-L-proline and camphorsulfonamide. Organocatalyst 11d is proven to be an efficient catalyst for the asymmetric Michael reaction of ketone and a series of chalcone-derived. Treatment of cyclohexanone with chalcone- deriveds which have electron-withdrawing group using organocatalyst 11d provided the desired Michael products with high chemical yields (up to 97% yield), excellent diastereoselectivities (up to 99/1 dr) and high levels of enantioselectivities (up to 93% ee) for syn- products.
