Abstract
Two-dimensional1H NMR spectroscopy (COSY, NOESY) in combination with the one-dimensional variant has been used to establish the conformation of the molecule of britannin — a sesquiterpene lactone of the ambrosane type. The comparative possibilities of one- and two-dimensional NMR spectroscopies in stereochemical investigations of sesquiterpene lactone with ambrosane skeletons are considered.
