New and improved routes to polysubstituted furans are described, together with a survey of their reactivity in cycloaddition reactions with oxyallyl carbocations, producing polysubstituted 8-oxabicyclo[3.2.1]oct-6-en-3-ones.

We describe a synthesis of a novel amino acid resembling helminthosporic acid. The route is short (six steps) and uses oxyallyl methodology to establish the correct regio- and stereochemistry in the required bicyclic system.
