Spectral Assignments and Reference Data Reassignment of NMR spectra and conformational study of the sesquiterpene lactone goyazensolide

摘要

We describe the reassigment of ~13C NMR signals of goyazensolide based upon 1D and 2D techniques, and discuss its conformation and stereochemistry as obtained from the analysis of its proton spin-spin coupling constants, NOE measurements and molecular mechanics calculations using MM3~* force field.
