A general and practical synthesis of (E)-α,β-unsaturated esters and ketones was achieved by the reaction of carbonyl compounds with ethyl-4,4,4-trifluoroacetoacetate and trifluoro-substituted 1,3-diketones in the presence of piperidine in dichloromethane at raoom temperature (≈40°C) with excellent stereoselectivity (see scheme).
