imidazolidinone auxiliary undergo diastereoselective alkylation and acylation reactions in moderate to good yields (9–91%) with high levels of stereocontrol (generally >95% de). Subsequent alkylation of these derivatives has been demonstrated for the production of non-racemic α,α-disubstituted amino acid precursors. Diastereoselective aldol reactions are also found to proceed with good yields and excellent stereocontrol
