Procedimiento
Monochloroborane-methyl sulfide (2.03 ml, 2.15 g, 19.5 mmol) was added dropwise to a stirred, cooled (0° C.) solution of compound 10 (2.96 g, 13.0 mmol) in THF (20 ml). The reaction mixture was stirred at 0° C. for 24 h, and a solution of hydrogen peroxide (13 ml, 30% in water) added dropwise and the reaction mixture stirred at 0° C. for 4 h, washed with water and the organic layer extracted into hexane/ethyl acetate (3×30 ml, 1:1). The combined extracts were washed with brine, dried (MgSO4) and the solvent removed in vacuo to yield colorless oil. The crude product was purified by column chromatography [silica gel eluted with hexane/ethyl acetate (4:1)] to yield a colorless oil.
