実験手順
To a solution of 1.74 g (7.76 mmol) of 4-(2,2-dimethylpropyl)-4-ethenylbenzene (from Step A) in 10 mL EtOAc and 10 mL H2O was added 8.30 g (38.8 mmol) of NaIO4 and 1 mg (0.0078 mmol) RuO2. The reaction mixture was heated to 40° C. for 30 min. The reaction mixture was cooled and stirred at rt for 16 hr. To the reaction mixture was added H2O and EtOAc, and layers were separated. The organic layer was dried and concentrated to dryness to provide 776 mg of the title compound: 1H NMR (500 Mhz) δ 0.91 (s, 9H), 2.53 (s, 2H), 7.12 (d, J=8.0, 2H), 7.84 (d, J=8.0, 2H); ESI-MS 193 (M+H); LC-1: 3.2 min.
