Abstract At− 60 C and in ether, the organolitium reagent produced by trimethylsilyl 4, 4- ethylenedioxypentanoate reacts with aldehydes and ketones, and gives the expected β- hydroxyacids. The β-ethylenic ketones are isolated when the condensation is carried out with aromatic aldehydes and ketones. This proves to be an efficient route for carbonyl olefination.
