Procedure for Preparation of 2h: To a solution of 2g (0.100 g, 0.158 mmol) in CH2Cl2 (10 mL) at r.t. was added MeCOOAg (0.0277 g, 0.166 mmol, 1.05 equiv, and the mixture was stirred in the dark at r.t. for one week. The residue was centrifuged for half an hour. Then the precipitate was filtered off and the filtrate was concentrated under reduced pressure to afford a yellow solid; mp 142-143°C; [α]D 25 121 (c, 0.108, CHCl3, IR (KBr, 3411, 2931, 2361, 1622, 1509, 1374, 1280, 1178, 1136, 905, 683 cm-1. 1H NMR (300 MHz, CDCl3, δ, 8.57 (d, J, 4.5 Hz, 1 H, 8.02 (s, 1 H, 7.66-7.81 (m, 4 H, 7.24-7.25 (m, 1 H, 6.94-6.98 (dd, J, 2.3, 9.2 Hz, 1 H, 6.49 (d, J, 12.5 Hz, 1 H, 6.37 (s, 1 H, 5.82-5.94 (sept, 1 H, 5.41 (d, J, 13.1 Hz, 1 H, 5.17-5.25 (m, 1 H, 4.70 (t, J, 10.5 Hz, 1 H, 4.52 t, J, 10.1 Hz, 1 H, 4.15

Typical Procedure: To a mixture of benzaldehyde (0.1 mmol, quaternary ammonium salt 2h (0.01 mmol, 10 mol, and Et3N (0.01 mmol) in CH2Cl2 (2 mL) under a N2 atmosphere, was added ethyl cyanoformate (0.15 mmol, 1.5 equiv) at -78°C. The reaction was monitored by TLC, and after the reaction time indicated in Table 3, the residue was directly purified by silica gel column chromatography (PE-Et2O, 10:1) to afford the title compound as a colorless oil in 96% yield with 67% ee as determined by HPLC analysis with a Chiralcel OD-H column [λ, 254 nm, hexane-2-propanol, 99:1, 1.0 mL/min, t R(major, 9.2 min, tR(minor, 10.9 min, α]D25, 6.49 (c, 0.154, CHCl3, 1H NMR (300 MHz, CDCl3, δ, 7.53-7.56 (m, 2 H, ArH, 745-7.49 (m, 3 H, ArH, 6.27 (s, 1 H, OCHCN, 4.26-4.32 m, 2 H, OCH 2, 1.34
