Notes:
The assignment of the proton and carbon spectra of some cyclopropane sesquiterpene lactone derivatives of helenalin and anhydroparthenin is presented. The interpretation of the spectra was achieved using 1H-13C two-dimensional heteronuclear chemical shift correlation, proton two-dimensional homonuclear correlated 2D and 2D-J, and some classical techniques. In particular, the spectra of halocyclopropane derivatives are discussed and compared with the spectra of the parent sesquiterpenes.
