A comprehensive collection of 13 C chemicalshifts of 159 tri‐ and tetracyclic quinolizidine alkaloids (sparteinederivatives) is presented. The data are discussed in terms ofsubstituent effects, molecular geometries and protonation effects.Some IR, 1 H and 15 N NMR and MS data areincluded. © 1998 John Wiley & Sons, Ltd.
