Kobayashi, S.; Wakabayashi, T.; Yasuda, M. J. Org. Chem. 1998, 63, 4868. These authors obtained aldehyde 7 by means of a three-step sequence which includes an asymmetric aldol reaction. We have prepared 7 from the known asymmetric dihydroxylation product of ethyl sorbate (Xu, D.; Crispino, G. A.; Sharpless, K. B. J. Am. Chem. Soc. 1992, 114, 7570). For details, see the Experimental Section.

Kobayashi, S.; Wakabayashi, T.; Yasuda, M. J. Org. Chem. 1998, 63, 4868. These authors obtained aldehyde 7 by means of a three-step sequence which includes an asymmetric aldol reaction. We have prepared 7 from the known asymmetric dihydroxylation product of ethyl sorbate (Xu, D.; Crispino, G. A.; Sharpless, K. B. J. Am. Chem. Soc. 1992, 114, 7570). For details, see the Experimental Section.

The chiral allylboranes used in this paper were prepared as described in the literature from allylmagnesium bromide and the appropriate enantiomer of the commercially available diiso-pinocampheylboron chloride. See: Ramachandran, P. V.; Chen, G.-M.; Brown, H. C. Tetrahedron Lett. 1997, 38, 2417. For a recent review on asymmetric allylborations, see: Ramachandran, P. V. Aldrichimica Acta 2002, 35, 23.

13C chemical shift value of the terminal methyl group at about 15 ppm. Lactones 5, 6, and synargentolide A show this signal above 16 ppm. This supports the conclusion that synargentolide A does not have an anti, anti relative configuration in its side chain as has lactone ii. (Chemical Presented)
