13C Chemical Shifts of Methylquinolizidines and Correlations with the Chemical Shifts of Methyl Substituted trans-Decalins

Abstract

13C chemical shifts are reported for quinolizidine and eight methylquinolizidines. Assignments of methylquinolizidine resonances are made with the assistance of the previously made assignments of quinolizidine, the methyl substituted trans-decalins and the methyl parameters of Grant. A more careful comparison of the quinolizidines with the trans-decalins is made through correlations with experimental data for four decalins and calculated data for six decalins.
