A vial was charged with aminoalcohol A (0.0063 g, 0.026 mmol). To the vial was added 1.68 mL of a stock solution containing trans-2-pentenal (0.34 g), t-butylbenzene internal standard (0.25 g), 1 M diethylzinc in hexane (8.0 mL), and toluene (4.0 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 80° C. on a Cyclodex B stationary phase. The product trans-4-hepten-3-yl acetate was formed 87% enantiomeric excess.
