Method for enhancing heterogeneous asymmetric selectivity and catalytic activity |
| abstract |
A method for enhancing heterogeneous asymmetric selectivity and catalytic activity belongs to the field of catalytic asymmetric organic synthesis technology, the preparation method of the invention are as follows: firstly preparing the chiral L -amino acids intercalated LDHs by coprecipitation or ion-exchange method; exfoliating the chiral L -amino acids intercalated LDHs into dispersed system of chiral L -amino acids attached to the inorganic LDH nanosheets; then coordinating the L -amino acids in the above dispersed systems with the metal centers for different types of asymmetric catalytic reactions. The results show that the as-prepared catalyst can enhance the asymmetric selectivity effectively. Compared with the homogeneous counterparts under the same reaction conditions, the catalyst exhibits relatively higher yields and largely improves the selectivity of the asymmetric reaction products; and thus the chiral compounds with a higher optical purity can be obtained. |
