    • Representative Experimental Procedure: (i) Preparation of 3e: To a THF solution (40 mL) of phenyl 4-(trimethylsilylethynyl)phenylmethyl sulfone (1.57 g, 4.8 mmol) was added LiHMDS (4.8 mL, 1.0 M THF solution, 4.8 mmol) at -78°C, and the mixture was stirred for 0.5 h. To this solution was added a THF solution (5 mL) of 2,5-diethyl-4-(4-methoxyphenylethynyl)benzaldehyde (1.16 g, 4.0 mmol, and the mixture was stirred for 1 h. After CIP(O)(OEt)2 (0.694 mL, 4.8 mmol) had been added, the mixture was stirred at r.t. for 2 h. After LiHMDS (20.0 mL, 1.0 M THF solution, 20.0 mmol) had been added at -78°C, the reaction mixture was stirred at -78°C for 1 h and then at 30°C for 17 h. After usual workup with EtOAc and aq NH4Cl, the organic layer was dried over MgSO4 and filtered. The solvents were evaporated, and the residue was chromatographed (CH2Cl 2-hexane, 3:7) to give 3e 1.73 g, 94, as a colorless solid
