Reaction Steps
Trichloroethyl chloroformate (2.5 mL) and pyridine (2.95 mL) are added to a solution of (4R,5S,6S)-1,1-diisopropoxy-5-hydroxy-2,2,4,6-tetramethyl-8-nonen-3-one (3.0 g) in 40 mL of CH2Cl2 at 0° C., and the mixture is stirred for 5 hours before pouring into sat. aq. NaCl and extracting with CH2Cl2. The extract is dried over Na2SO4, filtered, and evaporated. The product is purified by chromatography on SiO2 (2% ethyl acetate/hexanes).
