Notes:
The 13C-NMR. spectra of a number of colchicine derivatives are given comprising examples of the normal series (4→10), iso series (11→16) and colchicine series (17), which were either reported in the literature or obtained by partial synthesis or degradation reactions. The 13C-NMR. assignments were made by comparisons with known compounds and selective single-frequency offresonance decoupling experiments. Selective proton decoupling experiments have also allowed assignments of the H - C(11) and H - C(12) protons of the iso and colchicine series.
