Stereocontrolled Synthesis of Spirooxindoles Through Lewis Acid Promoted [5+2]-Annulation of Chiral Silylalcohols
[Image: see text] The enantioselective synthesis of stereochemically and structurally diverse spirocyclic oxindoles by [5+2]-annulation of chiral crotylsilanes bearing a primary alcohol is described. The annulation products were further elaborated to polycyclic oxindoles by Pd (0) catalysis.
