    • Typical Procedure for the Mukaiyama-Michael Reaction of 2-(Trimethylsilyloxy)furan (3) with α′- Phenylsulfonyl Enone 5a: To the flask of freshly prepared, 4R,5S)-diPhBox]Cu(OTf) 2 (5 mol, in CHCl3 (1 mL) was added a solution of α′-phenylsulfonyl enone 5a (0.11 mmol, 25 mg) in CHCl 3 (1 mL, After being stirred at r.t. for 0.5 h, the reaction mixture was cooled to 0°C, and the solution of 3 (0.22 mmol, 35 mg) in CHCl 3 (1 mL) was added to the reaction mixture. The reaction was maintained at the desired temperature until a complete consumption of the α′-phenylsulfonyl enone 5a as monitored by TLC. After completion of the reaction, the reaction was quenched with sat. aq NaHCO 3 solution, extracted with CH2Cl2, washed with H2O, dried over MgSO4, filtered, and concentrated under reduced pressure. The residue was purif
