In the past decade, C–H functionalization has been a very active topic of research in both academia and industry. When a H atom is replaced by an aryl (or heteroaryl) group, the transformation is termed “direct arylation”. This approach to the

A systematic investigation of the influence of substitution at positions C-2 and C-3 on the azulenone skeleton, based on NMR characterisation, is discussed with particular focus on the impact of the steric and electronic characteristics of substituen

Intramolecular rhodium(II)-catalysed aromatic addition (Buchner) reactions of a range of α- and β-substituted α-diazoketones are reported. Both steric and electronic effects are evident for the aromatic additions investigated. In general, highly e

Enantioselectivities of up to 95% ee have been achieved in the intramolecular Buchner reaction catalysed by copper bis(ox-azoline) complexes, the highest asymmetric inductions reported to date for this transformation. Significantly, use of a catalyst

Variation of the enantioselection of the copper-catalysed intramolecular Buchner reaction of diazoketones with the nature of the counterion is reported; significantly the presence of the non-coordinating BARF anion leads to enhanced enantioselectivit

Rhodium carboxylate catalyzed aromatic addition reactions of a range of diazoketones bearing methoxy-substituted aryl rings have been explored. While the existence of norcaradiene-cycloheptatriene equilibria in related compounds is well established,
