摘要
The 4,5-methano-L-proline was studied for the direct asymmetric aldol reaction of acetone or cyclohexanone with various aromatic and aliphaticaldehydes at -20 degrees C or 0 degrees C. A loading of only 5mol % of derivative la was employed in this catalytic system, and excellent enantioselectivities (up to 99% ee) and yields (up to 98% yield) could be achieved.
