“…R f = 0.33 (cyclohexane/EtOAc, 90:10). 33 Following GP1 performed with SMAHO 1c (131 mg, 0.75 mmol, 1.5 equiv) and p-toluoyl chloride (2c; 66 L, 0.5 mmol, 1.0 equiv), the desired product was obtained after purification by flash chromatography [silica gel, 50 mL, cyclohexane/EtOAc, 95:5 (250 mL), 90:10 (250 mL)] as a colorless oil; yield: 112 mg (90%). R f = 0.37 (cyclohexane/EtOAc, 90:10).…”
