Désilylation des indoles et synthese stereoselective de Biheterocyles contenant de l’indole et du 5,6-dihydropyridine-2(H)-ONE.

Abstract

This manuscript describes the reductive removal of silyl groups from N-protected indoles, using indium, magnesium, zinc and fer processes and new method for synthesis an N-tertButanesulfinylimines. In the main part: Chapters 1 and 2 we have reported the development of two efficient processes one for transforming a wide variety of indoles into the corresponding derivatives indoles in high yield, using a simple and soft protocol, and other to protect indoles which is our starting materials. Chapter 3 shows the deprotection of the silyl (triphenylsilyl) groups, In the second main part: we have described anew method for the synthesis of Biheterocycles Containing Indole and 5,6-Dihydropyridin-2(1H)-one or α-Methylene-β-butyrolactam. Using N-tert-Butanesulfinylimines as an important reactant.
