The synthesis and utility of the 3,3-dimethyl-5-substituted-2-pyrrolidinone 'Quat' chiral auxiliary in stereoselective enolate reactions of attached N-acyl side chains combined with the mild and non-racemising conditions required for the ultimate removal of the chiral side chain is described.
Synthesis of 5-substituted-3,3-dimethyl-2-pyrrolidinones: "Quat" chiral auxiliaries

The synthesis of a series of chiral auxiliaries, 5-substituted-3,3-dimethyl-2-pyrrolidinones, "quats", from L-glutamic acid is described. Efficient regeneration of the chiral auxiliaries from their N-pivaloyl derivatives is readily achieved with LiOH in THF-water at 20°C.
