Applications of Hypervalent Iodine Reagents: From Enantioselective Copper-Catalysed Arylation-Semipinacol Cascade to Methionine Functionalisation for Peptide Macrocyclisation
… substrate classes – including dihydropyran, indene and dihydronaphthalene moieties – are converted to enantioenriched beta-aryl spirocyclic ketones in excellent yields and enantioselectivities, and often as a single diastereomer. These are in turn useful functional handles for transformations …
