    • General procedure for asymmetric synthesis of a-hydroxy alkylphosphonates 3: To a stirred solution of a-keto phosphonate (1, 0.3 mmol), 4-nitrobenzoic acid (5.0 mg, 0.03 mmol), and catalyst I (5.8 mg, 0.015 mmol) in THF (0.7 mL) was added acetone (0.66 mL, 9 mmol). Reaction mixture was stirred for4-15 h at room temperature, concentrated, and purified by flash column chromatography (EtOAc) to afford the aldol product 3
