Spectral assignments and reference data: Identification and complete 1H and 13C spectral assignments for the triterpene fern-9(11)-en-28-oic acid
Magnetic Resonance in Chemistry
Date of Publication
The structure of the triterpene fern-9(11)-en-28-oic acid (1), was determined by concerted application of 2D methods, which also provided full 1H and 13C spectral assignments. Compounds 1 is a rare triterpene which has been isolated once before, as its methyl ester. Earlier errors in 13C spectral assignments are corrected.....
