aReaction conditions: 1a–y (0.1 mmol), amides (0.1 mmol), 3g (15 mol%), LiHMDS (12 mol%), 4 Å MS (70 mg) in toluene (2.0 mL); isolated yields.

bReaction performed at –78 °C.

cReaction performed with amide 2i. Diastereoisomeric ratio (dr) determined by 1H NMR and HPLC analysis. Enantiomeric excess (ee) determined by HPLC analysis on a chiral stationary phase.
