Rate limiting step precedes C-C bond formation in the archetypical proline-catalyzed intramolecular aldol reaction.

ABSTRACT: The archetypical proline-catalyzed intramolecular aldol reaction, the Hajos-Parrish-Eder-Sauer-Wiechert reaction, has served as a model reaction for the mechanistic study of the ever-growing class of proline-catalyzed conversions. Experimental measurements of the (13)C kinetic isotope effects for this reaction show conclusively that carbon-carbon bond formation is not rate-limiting.
