Structure Revision of Kiusianin C and Kiusianin D published in Chem.Pharm.Bull.,62,937(2014) is necessary

A more detailled analysis can be found in: Robien W. (2017) A Critical Evaluation of the Quality of Published 13C NMR Data in Natural Product Chemistry. In: Kinghorn A., Falk H., Gibbons S., Kobayashi J. (eds) Progress in the Chemistry of Organic Natural Products 105. Progress in the Chemistry of Organic Natural Products, vol 105. Springer, Cham

Erratum published on 01-July-2018 ( see here )


Kiusianin A, CAS-RN: 1650569-06-4

Structure proposal compatible with 13C-NMR data; signals for C13 and C14 are assumed to be misassigned



Kiusianin A, CAS-RN: 1650569-06-4

Structure proposal compatible with 13C-NMR data; signals for C13 and C14 reassigned



Kiusianin B, CAS-RN: 1650569-07-5

Structure proposal compatible with 13C-NMR data


Kiusianin C, CAS-RN: 1650569-08-6

Structure proposal NOT compatible with 13C-NMR data; Structure revision necessary; Structure revision gives known compound


  Original: 4.27 ppm at position 857  
  Best revised proposal: 0.79 ppm at position 1 in hitlist  

  Known structure: Recall from PUBCHEM


Kiusianin D, CAS-RN: 1650569-09-7

Structure proposal NOT compatible with 13C-NMR data; Structure revision necessary


  Original: 2.92 ppm at position 307  
  Best revised proposal: 1.46 ppm at position 7 in hitlist
