Abstract
A summary of informative examples involving the regioselective deprotonation of α-oxygenated ketones has been compiled from the literature and augmented by new findings from the authors' laboratory. The text provides a brief discussion of the complexity of the matter. The data are tabulated with regard to enolization both away from and toward the oxygen substituent, with subsequent capture at oxygen or carbon. The possible role of steric, electronic, and conformational factors is addressed in a manner that points up the need for a more detailed understanding of these enolizations as a general process.
