Meyer-Schuster-Type Rearrangement of Propargylic Alcohols into α-Selenoenals and -enones with Diselenides

We describe a mild and broadly applicable protocol for the preparation of a diverse array of multisubstituted α-selenoenals and -enones from readily accessible propargylic alcohols and diselenides. The transformation proceeds via the Selectfluor-promoted selenirenium pathway, which enables selenenylation/rearrangement of a variety of propargylic alcohols. Gram-scale experiments showed the potential of this synergistic protocol for practical application.

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

Preparations de composes α-arylselenocarbonyles a l'aide de morpholinoareneselenenamides

The reactivity of the morpholinoareneselenenamides 1 which are readily prepared from various diaryldiselenides, is investigated.The selenenamides 1 are good α-selenenylating agents for aliphatic aldehydes, α-ketoesters and conjugated enals yielding the α-

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.
