T1663

Typical Procedure (entry 1): A solution of (－)-α-bisabolol (22.2 mg, 0.1 mmol) in anhydrous dichloromethane (0.15 mL) is cooled to 0 °C and treated with anhydrous pyridine (31.6 mg, 0.4 mmol), followed by trifluoroacetic anhydride (42 mg, 0.2 mmol). The reaction mixture is stirred at 0 °C for 20 min and quenched with 1 N aqueous HCl. The resulting biphasic mixture is stirred vigorously at room temperature for 5 min and extracted twice with hexanes. The combined organic layers are washed with water followed by saturated aqueous NaHCO3, dried over anhydrous Na2SO4, and concentrated under reduced pressure. The resulting crude trifluoroacetate (32.0 mg, 0.1 mmol) is dissolved in TMSCN (0.1 mL), cooled to 0 °C, and treated drop-wise with a solution of anhydrous Sc(OTf)3 (1.5 mg, 0.003 mmol) in TMSCN (0.1 mL). The reaction mixture is left at 3 °C for 18 h and quenched with tetramethylethylenediamine (7.5 µl, 0.05 mmol). The resulting solution is concentrated under reduced pressure, and the residue is purified by flash column chromatography on silica gel (eluent: 35% dichloromethane in hexanes) to give 7-isocyano-7,8-dihydro-α-bisabolene (18.0 mg, 78% yield, dr 83:17) as a light yellow oil.
