21. Bismuth ( III ) iodide is a catalyst in the Mukaiyama aldol reaction. 22. It is used in aldol condensation reactions and base-catalyzed dehydration reactions. 23. It is the combination of the Michael Addition and the Aldol Condensation reaction. 24. This allows for the directed aldol reaction to produce a desired cross aldol. 25. This allows for the directed aldol reaction to produce a desired cross aldol . 26. The reaction is classified as an aldol condensation. 27. As for carbon compounds, catalysed Michael additions and aldol reactions can be used. 28. There is another aspect of aldol reaction that is influenced by the allylic strain. 29. This is the first example of an amino acid-catalyzed asymmetric aldol reaction. 30. The Michael-aldol sequence involves a Michael addition reaction and an aldol condensation.
