실험 절차

To a mixture of 4,4-Dimethylcyclohexanol (63.2 mg, 0.000493 mol), (R)-4-(6-hydroxynaphthalen-2-yl)-4-methyl-oxazolidin-2-one (100 mg, 0.0004 mol), triphenylphosphine (129 mg, 0.000493 mol), and tetrahydrofuran (4 mL, 0.05 mol), diisopropyl azodicarboxylate (0.0971 mL, 0.000493 mol) was added dropwise and was stirred at room temperature overnight. The mixture was diluted with EA and washed with 5% citric acid and brine then dried with magnesium sulfate and concentrated. The crude was taken up into DCM and subjected to ISCO combiflash purification with EtOAc/hexane (0-70) to give product.
