| Citation | Distinguished for his elegant work in the field of organic synthesis. He has provided original synthetic methods for an extensive range of natural compounds including complex fused ring terpenes, butyrolactones, polyenepyrones, pulvinones, ylidenebutenolides, cyclopentanoids and carotenoids. Varied methodologies have been applied including photochemistry, electrochemical generation of radicals and transition metal [Co(I)] mediation. Some of the synthetic work has led to precise structural and stereochemical definition of ill-defined compounds of biological importance. |
