Convergent total syntheses of dehydroambliol-A (1a), its unnatural Z isomer 1b, and ambliofuran (2) are described.The syntheses utilized 2-(3'-furyl)-1,3-dithiane (6) as a common intermediate.Analysis of their proton and carbon magnetic resonance spectra confirm that in the natural product dehydroambliol-A and in synthetic dehydroambliol-A the Δ7-bond possesses the E geometry, while in the unnatural isomer of dehydroambliol-A, the Δ7-bond is of the Z configuration.
