Chinese Journal of Chemistry 2013年第2期31卷 247-255页

作者： Tao Zhang Yunxiao Zhang Zaichun li zhongtai Song Hao liu Jingchao Tao College of Chemistry and Molecular Engineering Zhengzhou University 75 Daxue Road Zhengzhou Henan 450052 China

An approach based on combinations of various water compatible Lewis acids and lipophilic group containing amphiphilic prolinamide co-catalysts has been evaluated for the direct asymmetric Aldol reaction. From the broad screening of chloride salts from alkali metal to transition metal, liC1, ZnCI2 and SnCI2 lead to the highest stereoselectivities. The optimized catalytic conditions （10 mol% prolinamide with 10 mol% MC12 or 20 mol% liC1 at room temperature on water） gave anti-products with improved enantioselectivities （up to 99% ee） compared to the moderately stereoselective procedure based on prolinamide activation only.
