Complete 13C and 1H NMR assignments for a series of aromatic C‐ring derivatives of dehydroabietic acid

Complete 13C and 1H NMR spectral assignments for a series of derivatives of the naturally occurring C‐ring aromatic diterpene resin acid dehydroabietic acid have been made. The use of a combination of 1D and 2D NMR techniques allowed mostly unambiguous assignments of all 13C resonances. 1H resonances were also assigned.
