摘要

Résumé 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.
