Unraveling the unknown: Interpretation of methylene-proton NMR signals of 1,3-dimethyl-substituted alkyl chains allows for the assignment of the relative configuration of the two adjacent stereogenic centers (see figure). The new method is applicable in various NMR solvents and general trends and rules for assignment are shown. Natural products with unknown configuration can be assigned by using the information gained from already published spectra.
