Abstract

An NMR study of five highly functionalized and rearranged abietane diterpenoids is described. In addition to 1D NMR methods, including 1D NOESY spectra, 2D shift‐correlated experiments [^1^H, ^13^C‐gHSQC‐^1^J (C,H) and ^1^H, ^13^C‐gHMBC‐^n^J (C,H) (n = 2 and 3)] were used for the complete and unambiguous ^1^H and ^13^C chemical shift assignments of these substances.
