%0 Journal Article %T Piperidine Promoted Regioselective Synthesis of ¦Á, ¦Â-unsaturated Aldehydes %A A. H. Banday %J Pakistan Journal of Chemistry %D 2013 %I Chem Publisher %X An efficient, facile and regioselective synthesis of ¦Á,¦Â-unsaturated aldehydes from ¦Â-hydroxynitriles is reported. The reaction iscarried out using DIBAL-H and promoted by piperidine under dry conditions at a temperature of -78 oC and can be described as aconcomitant reduction-elimination reaction. The same reaction if carried out in the absence of piperidine gives mainly theuneliminated reduction product. The products formed are of immense importance as synthons in a large number of chemicalreactions and biological processes. %K ¦Á %K ¦Â-unsaturated aldehydes %K metal hydrides %K DIBAL-H %K ¦Â-hydroxynitriles %U https://www.pjchm.com/images/pdf/3_1_Paper_3.pdf
