It is noteworthy that the hydroxylated quinolizidines 9, 20, and 21 described here possess the same or similar skeleton as naturally occurring myrtine from plants and xestosin found from marine sponges. See: (a) Slosse, P.; Hootelé, C. Tetrahedron 1981, 37, 4287-4294.

We attempted to record NMR spectra at 60°C; unfortunately, epimerization at C4′ likely occurred in both 20 and 21, as indicated by the proportional decrease of 4′-Me signals of 20 and 21 and by the appearance of a methyl resonance at 1.24 ppm J, 5.9 Hz, See ref 32a
