Selenylated dienes: synthesis, stereochemical studies by 77Se NMR, and transformation into functionalized allenes

2-Phenylselanyl-1,3-dienes 3-8 were prepared by a Wittig or Wittig-Horner-Emmons procedure starting from α-phenylselanyl α,β-unsaturated aldehydes. Ratio and configuration of each diene isomers were determined by 77Se and 1H NMR. The

SYNTHESE D'α-HYDROXYALLENES α-FONCTIONNALISES A PARTIR D'α-PHENYLSELENOENALS

Morpholinobenzeneselenenamide (MBSe) react with enals to form α-phenylselenoenals which undergo Wittig and Horner reactions.We synthetise 1-substituted 3-phenylseleno-1,3-butadienes.Oxidation and subsequent 2,3-sigmatropic rearrangement lead to α-fonctionnalized α-hydroxyallenes.This compounds give access to 2,5 dihydrofurans.
