Procedure
To a solution of 105 (2.67 g, 8.29 mmol) in tert-butanol (80 mL) and water (80 mL) was added methanesulfonamide (0.79 g, 8.29 mmol, Sigma-Aldrich). The mixture was cooled to 5° C. and AD-mix-α (11.50 g, 8.29 mmol) was added to form a reaction mixture. After warming the reaction mixture to a temperature of about 25° C. and stirring for 16 hours, excess solid sodium sulfite was added and the resulting slurry was allowed to stir at 15° C. for 30 min. The mixture was extracted twice with EtOAc. The organic portions were combined, washed with brine, dried (Na2SO4), and concentrated under reduced pressure. The residue was chromatographed on a silica gel column eluted with 50:50 EtOAc:hexanes and 70:30 EtOAc:hexanes to provide 106 as a solid (>99% yield).
