Using modern NMR techniques, including 1 H 13 C and 1 H 15 N heteronuclear correlation experiments, the complete and unambiguous 1 H, 13 C, and 15 N NMR chemical shift assignments of annomontine, methoxyannomontine, and N ‐hydroxyannomontine pyrimidine‐β‐carboline alkaloids were performed. All 1 H 1 H scalar coupling constants and signal multiplicities were determined, and all nOe observations were also included. Copyright © 2008 John Wiley & Sons, Ltd.
