Abstract
The NMR-Spectra of substituted benzylidene barbituric acids, benzylidene dimethylbarbituric acids and some 1,4-and 1,3-cycloaddition products are reported. The signals of the olefinic protons and the N−CH3-signals depend on the conformation of the compounds. The NMR-Spectra of the anions are also given.
