Abstract

AbstractThe Strychnos alkaloids have been the focal point of considerable synthetic and spectroscopic effort. We now report the 15N chemical shifts and long‐range 1H‐15N coupling pathways of strychnine, brucine, and holstiine at natural abundance. Long‐range coupling pathways were established using a gradient‐enhanced HMQC sequence optimized for the observation of 1H‐15N long‐range couplings.
