    • All hydroxypolyene substrates were produced with >95% E or Z purity, with the exception of compound 29, which was prepared as a 1.5:1 mixture of E/Z isomers at the terminal alkene. Please see the Supporting Information for the preparation and characterization of hydroxypolyene substrates.

    • note
    • Small amounts of the diastereomeric lactones produced in each case (14 from the reaction of 11; 13 from the reaction of 12) may be attributed to either chromium-mediated epoxidation or alkene isomerization prior to syn-oxidative cyclization. Gas chromatography analysis of commercial neryl-and geranylacetone (precursors to 11 and 12) revealed that each were contaminated with only 1.2-1.5% of the other isomeric compound, which accounts for some but not all of the slight loss of stereospecificity observed in these reactions.

    • note
    • We have noticed that the diastereomer ratios obtained with the dichloroacetylperrhenate reagents varied slightly between experiments, suggesting that there may be a concentration dependence of acid on the stereoselectivity of syn-oxidative cyclization reactions.

    • After considerable difficulty we obtained small amounts of the Mosher esters from reaction of 49 with (R)- and (S)-MTPA (Rieser, M. J.; Hui, Y.-h.; Rupprecht, J. K.; Kozlowski, J. F.; Wood, K. V.; McLaughlin, J. L.; Hanson, P. R.; Zhuang, Z.; Hoye, T. R. J. Am. Chem. Soc. 1992, 114, 10203); however, the chemical shift differences at H14 for each Mosher ester were less than 0.01 ppm. A similarly minute difference in chemical shift was observed in goniocin (ref 3a).
