Popis: |
Novel (4 R )-HO-(2 S )-Pro-( S )-Val derivative tagged to 1-methylimidazolium cation and P F 6 ¯ anion efficiently catalyzes asymmetric aldol reactions of cyclic ketones with aromatic aldehydes in aqueous environment to afford the corresponding aldols in high yield with moderate to high anti -diastereo- ( dr up to 99: 1) and enantioselectivity (up to 98% ee ). The catalyst was recycled 9 times in the same reaction without any decrease in selectivity values. |
