✦ Synopsis

13C NMR spectral data for nine tetrahydro-1.5-benzodiazepin-2-ones are reported and the chemical shift assignments are discussed. The steric energies of the E and Z isomers of formyl derivatives were estimated by computer molecular modeling

The 13C NMR spectral data for 18 dihydropyrimidinediones and their 2-thio analogues are presented. The influence of substituents on the shielding of neighbouring atoms was analysed and the resonances were unambiguously assigned. 13C NMR spectroscopy was shown to be useful for structural determinatio

Because of the upsurge of interest in polychlorobuta-1,3-diene derivatives as uncommon contaminants in underground water, seven congeners, the three pentachloro-and four tetrachloro-[(Z)-and (E)-1,1,3,4tetrachloro-, 1,1,4,4-tetrachloro-and (Z,Z)-1,2,3,4-tetrachloro]buta-1,3-dienes, were synthesized

Selected 1,4-and 1,5-benzoheterazepinones, prepared by the Schmidt rearrangement of flavanone analogues, were converted to the corresponding thiolactam derivatives using phosphorus pentasulfide. The proton and carbon chemical shifts of the thiolactam derivatives are compared with those of their lact
