We tried to cyclizise 1 with several Nazarov reagents (1-phenylsulfinyl-3-buten-2-one, 1-phenylthio-3-buten-2-one, 1-phenylsulfinyl-4-(triethylsilyl)-3-buten-2-one, 1-phenylsulfoxyl-4-(triethylsilyl)-3-buten-2-one, 1-phenylsulfinyl-4-(trimethylsilyl)-3-buten-2-one, methyl-5-(trimethylsilyl)-3-oxo-4-pentenoate), however with no success.

During the preparation of this manuscript, Ziegler et al. published a paper in which they used racemic 8 for the total synthesis of (±)-Scopadulcic acid A and B and (±)-Scopadulciol as well as reporting preliminary studies about the synthesis of chiral 8 (Ziegler, E F., Wallace, O. B. J. Org. Chem. 1995, 60, 3626).

8 d 5.8 (m, 1H), 5.2 (m, 3H), 2.0-2.9 (m, 12H). Those data are somewhat erroneous in that H′-3 at 1.70-1.66 ppm was not reported and instead was assumed to be underneath the unresolved multiples between 2.0-2.9 ppm. However, COSY and HSC spectra clearly revealed that this multiplet at 1.70-1.66 ppm has to be assigned to H′-3.
