The first synthesis of auxofuran, a newly discovered auxin-like signaling molecule of streptomycetes, has been achieved in seven steps and 59% overall yield from commercial starting materials. Central to the synthetic route is a click–unclick Diels–Alder cycloaddition/cycloreversion regimen enabling rapid access to an advanced intermediate from an unactivated alkyne.
