Abstract
Alkylation of 2-phenyl-3-piperidone (17) with methyl iodide or methyl acrylate furnished the 4,4-dialkylated derivatives (18) or (19), respe ctively. This unexpected enolization towards the less substituted form can be interpreted considering the appreciable steric strain which wo uld exist in the more substituted enolate (21).
