An NMR and computational study of diazepinediones
The structure and ring-inversion barriers of several imidazodiazepinediones and benzodiazepinediones are studied. The barrier for one of each type is experimentally determined by NMR and calculations are carried out with the AM1 semi-empirical method. For comparison, calculations are also carried out on several imidazodiazepines and benzodiazepines. © 1989
