I of this simple compound has been reported: and that involves a Diels-Alder cycloaddition of cyclopentadiene with 4-(benzyloxy)-3-buten-2-one followed by hydrogenation and dehydration. This provides the target molecule in 48% overall yield. Unfortunately, extension of this direct synthesis to less reactive nitrogen-containing dienes such as substituted pyrroles in place of cyclopentadiene is not possible. Another straightforward preparation ...
