    • 15 (1.64 mmol) was added at 0 °C to N-phosphinoylimine 4a (0.411 mmol) in anhydrous toluene (2 mL). The reaction mixture was stirred at room temperature for 1 h. The reaction was quenched by the addition of 3 ml of a 2 M Rochelle salt solution and the reaction mixture was stirred for 15 min at rt. The aqueous layer was separated and extracted with ethyl acetate. The organic layers were mixed and washed successively with water and brine. After drying, the solvent was evaporated under reduced pressure, and the oily residue was purified by column chromatography on silica gel (ether/n-heptane 6/4) to leave 5 as a white solid (56%).
