The first synthesis of the antiinflammatory marine natural product luffariellolide has been achieved by a convergent pathway involving sp3-sp3 cross-coupling and silyloxyfuran oxyfunctionalisation as key steps. An illustration of the inherent flexibility of this strategy is provided by a simple synthesis of α,β-acariolide and its γ-hydroxylated derivative from a common silyloxyfuran precursor.

2-Trialkylsilyloxyfurans react rapidly with dimethyldioxirane at -78 °C to provide trialkylsilyl (Z)-4-oxo-2-alkenoates whose hydrolysis delivers γ-hydroxybutenolides with high efficiency; a short synthesis of a naturally occurring monoterpene γ-hydroxybutenolide (4) is reported.
