Reaction Steps

22.5 ml (113 mmol) of triethyl phosphono-acetate are dissolved in 100 ml of THF. 4.5 g (113 mmol) of 60% sodium hydride are then added, and the medium is stirred for 30 minutes at ambient temperature. A solution of 20 g (75.6 mmol) of 3-(tert-butyldimethylsilanyloxy)propan-1-one in 100 ml of THF is then added drop by drop. The medium is stirred for 6 hours, then treated with water and extracted with ethyl acetate. The residue obtained is purified by chromatography on silica gel (eluent ethyl acetate 10-heptane 90). A yellow oil is obtained (m=7.6 g; Y=30%).
