| Abstract: | DEPT and 2D NMR techniques including 1H-1H COSY, 1H-13C COSY, NOESY and 1H-13C COLOC were used to investigate the structures of two sesquiterpene alkaloids with polyester groups. It worth noted specially that 1H -13C COLOC is a very powerful tool for the location of each substituent on the skeleton. The stereo structures were deduced from the coupling constants in
1H NMR and NOESY. |
