    • note
    • NOESY experiment on the diastereoisomeric mixture of the alcohols 5 showed correlation peaks between the methyl group at position 3 and the hydrogens on the furyl ring for the most abundant diastereoisomer, thus confirming that these two groups are in a cis relationship. The absence of any peak of correlation for the methyl group with hydrogens on the furyl ring was observed in the case of the minor diastereoisomer, which confirmed that the two groups are in a trans relationship.

    • The tertiary 2′-furyl-2-norbornyl cation was found to be stabilized by the charge-delocalizing ability of the furyl system. It has been reported that there is substantial π-bond character between C-2 of the furyl moiety and the cationic carbon, see: G. A. Olah, A. L. Berrier, G. K. S. Prakash, J. Org. Chem. 1982, 47, 3903.

    • Alcohol exo-5 was recovered during the purification procedure (flash chromatography) in 65-75% yield and recycled for the synthesis of 3, thus making the entire process more convenient.
