A Green Enantioselective Aldol Condensation for the Undergraduate Organic Laboratory George D. Bennett
The proline-catalyzed aldol condensation between acetone and isobutyraldehyde proceeds in good yield and with high enantioselectivity at room temperature. This multi-week experiment also illustrates a number of principles and trade-offs of green chemistry.
