General Procedure for the Reaction of Oxime Ether 1
To a microtube containing oxime ether 1 (50 mg, 0.26 mmol), i-PrI (1.3 mL, 1.3 mmol), indium salt (2.6 mmol), copper salt (0.26 mmol), and MeOH (0.2 mL) H2O was added dropwise (0.4 mL) at r.t. After the reaction mixture was vigorously stirred at the same temperature for 1 h, i-PrI (1.3 mL, 1.3 mmol) was added to the reaction mixture. After being vigorously stirred at the same temperature for 1 h, the reaction mixture was diluted with aq 36% potassium sodium (+)-tartrate and then extracted with EtOAc. The organic phase was dried over MgSO4 and concentrated under reduced pressure. Purification of the residue by preparative TLC (hexane-EtOAc, 4:1) afforded the adduct 2 4b in the yields shown in Table  [¹] .
