Abstract
The C-13 NMR spectral data for 18 dihydropyrimidinediones and their 2- thio analogues are presented. The influence of substituents on the shi elding of neighbouring atoms was analysed and the resonances were unam biguously assigned. C-13 NMR spectroscopy was shown to be useful for s tructural determination of dihydropyrimidinediones and thioanalogues a nd allowed the facile distinction of otherwise similar compounds from the two classes.
