Reaction Steps

A vial was charged with aminoalcohol 1 (0.0074 g, 0.026 mmol) prepared as in Example 1. To the vial was added 1.60 mL of a stock solution containing trimethylacetaldehyde (0.26 g), chlorobenzene internal standard (0.26 g), 1 M diethylzinc in hexane (6.0 mL), and toluene (3.0 mL). After 48 h, acetic anhydride (0.200 mL) was added. After an additional 72 h, a sample of the solution was analyzed by gas chromatography at 70° C. on a Cyclodex B stationary phase. The product 3-acetoxy-2,2-dimethylpentane was formed in 73% yield and 98% enantiomeric excess. The identity and yield of the product was established by comparison with an authentic sample prepared by treatment of racemic 2-methyl-3-pentanol with acetic anhydride.
