(E)-hept-2-en-1-ol

Conditions: temp:-60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Under argon atmosphere, to anhydrous dichloromethane suspension (150 ml) containing 3.4 g of Molecular Sieves 4A were added 3.3 g (14.08 mmol) of diisopropyl D-(−)-tartarate, 3.3 g (11.73 mmol) of titanium tetraisopropoxide and 13.4 g (117.30 mmol) of (trans)-2-heptene-1-ol at −30 to −40° C. and the mixture was stirred for 10 minutes. The reaction mixture was cooled to −60° C., and under stirring, 105 ml of a toluene solution containing 2.23M of t-butylhydroperoxide was added dropwise to the mixture over 20 minutes, and the temperature of the resulting mixture was returned to room temperature over 2 hours. After completion of the reaction, the reaction mixture was added to an aqueous solution (400 ml) containing iron (III) sulfate heptahydrate (80 g) and L-tartaric acid (40 g), and the resulting mixture was extracted with dichloromethane (400 ml). The organic layer was washed with a saturated NaCl solution, dried over anhydrous sodium sulfate, and the solvent was removed under reduced pressure. To the residue were added ether (400 ml) and 1N-sodium hydroxide (200 ml), and the mixture was stirred at room temperature for one hour. After completion of the reaction, the organic layer was separated, and the aqueous layer was extracted with ether (50 ml). The organic layer was washed with a saturated NaCl solution, dried over anhydrous sodium sulfate, and the solvent was removed under reduced pressure. The residue was evaporated under reduced pressure to obtain 11.6 g (Yield: 76.2%) of the title compound. under stirring was added dropwise to the mixture over 20 minutes the temperature of the resulting mixture was returned to room temperature over 2 hours After completion of the reaction the resulting mixture was extracted with dichloromethane (400 ml) The organic layer was washed with a saturated NaCl solution dried over anhydrous sodium sulfate the solvent was removed under reduced pressure To the residue were added ether (400 ml) and 1N-sodium hydroxide (200 ml) the mixture was stirred at room temperature for one hour After completion of the reaction the organic layer was separated the aqueous layer was extracted with ether (50 ml) The organic layer was washed with a saturated NaCl solution dried over anhydrous sodium sulfate the solvent was removed under reduced pressure The residue was evaporated under reduced pressure
