Palladium-catalysed intramolecular asymmetric ene reaction of chiral allylic sulphones via chiral allylic sulphinate–sulphone rearrangements
Abstract
The chirality of the sulphinate sulphur atoms has been transferred to the carbon centres in chiral allylic sulphinate–sulphone rearrangements, followed by palladium-catalysed intramolecular ene reactions of the chiral allylic sulphones obtained, with high stereospecificity.
