실험 절차

To a suspension of NaH (0.25 g, 6.18 mmol) in 7.4 mL DMSO (dried over molecular sieves) at room temperature under N2 was added trimethylsulfoxonium iodide (1.50 g, 6.85 mmol). The mixture was stirred for 1.5 hr. A solution of (17β)-3-oxo-N-[2-(trifluoromethyl)phenyl]androsta-4,6-diene-17-carboxamide (5-1) (0.68 g, 1.49 mmol) in 10 mL DMSO was added slowly. The solution was stirred at room temperature overnight. The reaction was then quenched by dropwise addition of 10% KHSO4 solution and extracted with CHCl3. The organic phase was washed with 10% KHSO4 solution, saturated NaHCO3 solution, and brine, then dried with MgSO4. After removal of the solvent, the residue was purified by chiral preparative HPLC (Chiralpak AD, 85% Hexanes (0.1% diethylamine); 15% 2-propanol) to yield the desired resolved products 6-6and 6-2.
