Oxabicyclo[2.2.1]norbornenes constitute a convenient and readily cleaved linker for solid-phase organic synthesis. A simple and inexpensive furfuryl-substituted resin has been shown to capture and release maleimide dienophiles under conditions compatible with intermediate synthetic steps. The synthesis of β-amino, -thiophenoxy, and -hydrazino alcohols by epoxide ring opening, and maleimide-functionalized

A simple route to activated dienes generated from enone precursors at the N-terminal of immobilised dipeptides is described. The dienes are subjected to reaction with a maleimide dieneophile containing a protected amino functionality for continued peptide synthesis. The reactions are pure and quantitative with dienes generated at the N-terminal of a variety of different dipeptides, including substrates
