反応手順
A solution of 590 mL (27.7 mmol) of dimethyldioxirane, 0.047M in acetone (prepared by the procedure of Eaton and Wicks, J. Org. Chem. 1988, 53, 5353) is added via a cannula to a 0° C. solution of 12.1 g (27.7 mmol) of 2,6-diphenyl-4-piperidyl laurate in 200 mL of acetone. After stirring for 10 minutes at 0° C., the reaction mixture is concentrated under reduced pressure and the residue is recrystallized from methanol to yield 9.7 g (78% yield) of the title compound as a white solid: mp 89°-90° C.
