Abstract

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 Leu-enkephalin by ...
