    • note
    • The selective production of both stereochemistries would be significant, since both stereochemistries were observed in this family of natural products. While the exo-oriented compounds belong to the quinocarcin family (lemonomycin, quinocarcin and tetrazomine), the corresponding endo-oriented compounds belong to the naphthyridinomycin family (naphthyridinomycin and dnacins). See ref. 2.

    • note
    • Use of the Ugi 4-CC reaction in methanol or other solvents resulted in low yield due to the large amount of by-products, generated from solvolysis and/or hydrolysis of the intermediates.

    • A similar acyliminium cation mediated intramolecular cyclization has been reported and the exo-oriented bicyclo[3.2.1]octane ring system was also obtained. See: (a) T. Fukuyama and J. J. Nunes, J. Am. Chem. Soc., 1988, 110, 5196;

    • A similar cross-metathesis with the allyl derivative of 13 (without the terminal methyl group) resulted in a low yield due to decomposition.

    • The stereochemistry was confirmed by a strong NOE between H-4 and H-15 in the Boc derivative of 19.
