Abstract

Chapter one describes two efficient synthesis methods for the preparation of functionalised phosphonium salts. The first method utilises aryl radicals generated by a photo-induced decomposition of diaryliodonium salts, with the second method generating aryl radicals from arylboronic acids and manganese acetate. In both cases a broad substrate scope is demonstrated with respect to both the phosphorus and arylating species.

Chapter two describes approaches to the total synthesis of plant sesqui-neolignans. The synthesis of macranthol was achieved in 5 steps from commercially available 4-allylanisole in 7% yield. As well as the first synthesis of the core [4.3.0] ring structure of the fargenin/fargenone family of natural products.
