実験手順: To a solution of 2-methylcyclohexanecarboxylic acid (6.00 mL, 42.6 mmol, mixture of cis and trans) in DCM (60 mL) was added oxalyl chloride (4.80 mL, 55.3 mmol) followed by DMF (0.03 mL, 0.4 mmol). The reaction was stirred at ambient temperature for about 4 h before it was concentrated under reduced pressure to a constant weight to afford 2-methylcyclohexanecarbonyl chloride (mixture of diastereomers) as a yellow oil (7.0 g, 97%): 1H NMR (400 MHz, CDCl3) δ 2.98-2.94 (m, 1H), 2.39-2.35 (m, 1H), 1.91-1.82 (m, 1H), 1.79-1.72 (m, 1H), 1.69-1.60 (m, 2H), 1.57-1.47 (m, 2H), 1.42-1.36 (m, 1H), 1.34-1.26 (m, 1H), 1.04-0.96 (m, 3H). was concentrated under reduced pressure to a constant weight
