    • Annulation methods involving either carbon or oxygen radical addition followed by cyclization are also potential strategies. However, examples using this method have not been reported.

    • Intermolecular radical addition to β-alkoxy enoates under a variety of conditions fails to provide any product [Lewis acid activation, reactions at low (-78 or 0 °C) or high temperatures (80 °C, syringe pump addition)].

    • The lack of NOE between the C-2 methine and C-6 methylene hydrogen suggests that the isopropyl is in an axial orientation. This may reflect buttressing effects between this substituent and the diester functionality at C-3.
