The barriers for intramolecular aldol reactions (catalyzed as well as uncatalyzed processes) are generally found in the range of 5 to 30 kcal/mol. See: 2000 J. Am. Chem. Soc. 2001 123 12911 J. Am. Chem. Soc. 2005 127 11294 The computed trends are found to be the same when solvent single-point energies as well as the free energies in the gas phase are compared.
