Impacts of Steric Compression, Protonation, and Intramolecular Hydrogen Bonding on the (15)N NMR Spectroscopy of Norditerpenoid Alkaloids and Their Piperidine-Ring Analogues
[Image: see text] (1)H–(15)N HMBC spectra of norditerpenoid alkaloids and their synthetic azabicyclic analogues were obtained to investigate the impacts of the through-space effect of steric compression, protonation, and formation of intramolecular hydrogen bonding on the (15)N NMR spectroscopy of t...
