Abstract
New α-allylation reactions were performed of CH-acids with carbonyl groups (β-ketoacetic esters, phenylacetone, β-tetralone, ethyl acetate and its α-substituted derivatives) using as deprotonating reagents depending on the substrate acidity sodium hydride, potassium tert-butilate, and sodium bis(trimethylsilyl)-amide. BrCH2CH=CRR′ (R= R′ = H, Me; R = Me, R′ = CH2Ph, CH2CH2Ph) and BrCH2CH=X (X = cyclohexanylidene, 4-pyranylidene, 4-N-Boc-piperidinylidene) were applied as allylating agents.
