Abstract
Diastereoselectivity which is induced by the use of 2-imidazolidinone auxiliaries is greatly dependent on the N-substituents of the heterocycles, among which the bulky arenesulfonyl group is the moiety of choice. Reactions of this type afford an excellent level of diastereoselection in the methylation of N′-butyryl-2-imidazolidinones via the metal enolates.
