The arylation of 2-pyrones and related heterocycles
2-Pyrones, and related heterocycles such as 2-pyridones, 2-coumarins and 2- quinolones, are useful model substrates to test a novel methodology due to their varied chemical properties. In addition, these moieties possess broad spectrum biological activity. Chapter 1 provides a review of C–H …

Direct arylation of 2-pyrones, coumarins, 2-pyridinones and 2-quinolones
… 1 involves a discussion of the prevalence of 2-pyrones and 2-pyridinones and their corresponding analogues in naturally occurring biologically active compounds. We review their chemical and biosynthesis, as well further elaboration of the core compounds. The mechanism of traditional …

Towards the total synthesis of Phacelocarpus-2-pyrone A: Novel 2-pyrone chemistry
… for the synthesis of functionalised 2-pyrones. Initial studies focused on the synthesis of the natural product and the applications of Pd-catalysed cross-coupling reactions using the interesting palladium catalyst, CatCat. Key findings in the studies towards the natural product include: …

Palladium and manganese catalysis in C-H activation
… methods involving the C-H activation of 2-pyrones and 2-coumarins. The cyclisation of 2-pyrones and 2-coumarins via double C-H activation is described in Chapter 2 of this thesis. The synthesis of a library of 2-pyrone and 2-coumarin substrates was achieved using this methodology. Excellent …
