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.
