Fig. 3: Substrate scope with respect to the aldimine esters.

Reaction conditions: (i) 1a (0.4 mmol), 2a (0.2 mmol), L11-Pd (4 mol%), L3-Cu (5 mol%), Et₃N (200 mol%), THF (0.5 mL), 30 °C, 48 h; (ii) citric acid (10 wt%, 4 mL). Isolated yields are provided. The ee values were determined by HPLC on a column with a chiral stationary phase.
