developed (4+3) cycloaddition between dienes and furfuryl alcohols, as precursors of oxyallyl‐type cations, has been used as a key step in the racemic syntheses of two natural products: frondosin B and liphagal. This work demonstrates the synthetic potential of this cycloaddition reaction, and offers a short synthetic route to an interesting family of natural products.
