The 13C-NMR. spectra of a number of colchicine derivatives are given comprising examples of the normal series (410), iso series (1116) 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
的13 C-NMR。给出了许多秋水仙碱衍生物的光谱,包括正常系列(410),iso系列(1116)和秋水仙碱系列(17)的实例,其在文献中已报道或通过部分合成或降解反应获得。的13 C-NMR。通过与已知化合物的比较和选择性单频非共振去耦实验进行分配。选择性质子解耦实验还允许分配iso和秋水仙碱系列的H -C(11)和H- C(12)质子。
