Palladium(II)-catalysed Intramolecular Oxypalladation/Functionalisation of Carbohydrate-derived Cyclic Alkenes. Regioselective Formation of Substituted Di- and Tetra-hydropyrans
Abstract
A palladium(II)-promoted domino process converts easily prepared pseudoglycals into highly functionalised, chiral di- and tetra-hydropyran structures in high yields.
