Participants

Reaction Steps

TMSCN (0.13 mL, 0.96 mmol) was added to a mixture of compound 139 (70 mg, 0.32 mmol), cyclobutanone (0.15 mL, 1.92 mmol) and ZnCl2 (4 mg, 0.03 mmol) with stirring. The reaction mixture was stirred at room temperature for 5 h, and concentrated in vacuo. The residue was diluted with water, and extracted with DCM. The combined organic layers were washed with brine, dried over Na2SO4 and concentrated to dryness to give compound 141 (90 mg) as a light yellow oil. The crude product was used directly for the next step without purification.
