A SIMPLE SYNTHESIS OF α,β-UNSATURATED ALDEHYDES BY 1,3-CARBONYL TRANSPOSITION THROUGH ONE CARBON HOMOLOGATION

Article abstract of DOI:10.1016/S0040-4039(00)98557-5

α,β-Unsaturated aldehydes are conveniently prepared from ketones through their β-diethoxymethyl derivatives by sodium borohydride reduction followed by acid-catalysed rearrangement of the resulting diacetal carbinols.
