Participants

Reaction Steps

1-Allyl-4-(tert-butyl-diphenyl-silanyloxy)-cyclohexanecarboxylic acid ethyl ester (5 g, 11.1 mmol) was dissolved in 2-propanol (100 mL) and water (50 mL). To this was added an aqueous solution of NaIO4 (5.94 g, 27.8 mmol) in water (50 mL), followed by addition of OsO4 (0.025 g, crystals, in one portion). The reaction mixture was allowed to stir for 16 hours at rt. The reaction mixture was poured into ice water (50 mL) and ethyl acetate (EtOAc) (60 mL). The layers were separated and the aqueous layer was extracted with EtOAc (3×50 mL). The combined organic layers were washed with brine, and concentrated to dryness. The resulting product was then purified over silica gel column eluting with ethyl acetate in heptanes (0-60%) to afford 4.45 g (87%) of the title compound.
