Abstract
The Strychnos alkaloids have been the focal point of considerable synt hetic and spectroscopic effort. We now report the N-15 chemical shifts and long-range H-1-N-15 coupling pathways of strychnine, brucine, and holstiine at natural abundance. Long-range coupling pathways were est ablished using a gradient-enhanced HMQC sequence optimized for the obs ervation of H-1-N-15 long-range couplings.
