Regioselective Michael-induced cyclisation of ?- and d-hydroxy vinyl sulfides and vinyl dithiocarbamates

Tetrahedron Letters 46 (25) 4349-4352

par Administrateur - publié le

Abstract :

We herein describe the unprecedented use of heteroaryl vinyl sulfides and vinyl dithiocarbamates as hetero-Michael addition acceptors. Combined chelating and electron-withdrawing effects Lire Postulated to stabilise the transient anionic species and allow smooth Michael-induced ring closure to produce diversely functionalised C-glycosides.
