    • Procedure for the Synthesis of Compound 4: To a solution of n-BuLi (2.164 M in hexane, 1.39 mL, 3.0 mmol) at -78°C was added a solution of furan (245 mg, 3.6 mmol) in THF (5 mL, and the mixture was stirred at r.t. for 3 h. The mixture was then cooled to -78°C, and a solution of tert-butanesulfinyl imine 2 (0.5 M in THF, 4.0 mL, 2.0 mmol) was added via syringe over 10 min. The reaction mixture was stirred at -78°C for 3 h and quenched with a sat. NH4Cl solution (2 mL, The solvent was evaporated under reduced pressure and the residue was treated with H 2O (10 mL, The mixture was extracted with EtOAc, dried over anhyd Na2SO4 and concentrated. Flash chromatography of the residue (petroleum ether-EtOAc, 6:1) afforded compound 4 (96, as a white solid; mp 81-82°C; [α]D20 +3 (c, 0.5, CH2Cl2, IR KBr, 3235, 2935, 1462, 1377, 1210, 1157, 1
