Reaction Steps
A solution of triethyl phosphonoacetate (1.62 mL) in acetonitrile (8 mL) was treated with lithium chloride (0.43 g) and then cooled to 0° C. and triethylamine (1.23 mL) added dropwise as a solution in acetonitrile (2.5 mL). The reaction mixture was stirred at 0° C. for 15 minutes then a solution of 2,2-dimethyl-7-(tetrahydro-pyran-2-yloxy)-heptanal (1.65 g) in acetonitrile (6 mL) was added. The resultant mixture was allowed to warm to room temperature and was stirred for 3 hours before treating with saturated aqueous ammonium chloride solution, ether and water. The layers were separated and the aqueous phase was extracted with ether (×2) and the combined organics were washed with brine, dried over magnesium sulphate, filtered and evaporated to afford the crude product. Purification was by silica gel chromatography eluting with 0 to 40% ethyl acetate in cyclohexane to afford the subtitled compound as a colourless oil. Yield 0.89 g.
