摘要
Enantiopure Delta(2)-pyrazolines and Delta(2)-1,2,4-triazolines fused to the 1,4-benzodiazepine moiety, as well as Delta(2)-pyrazolines annulated to the 1,5-benzoxazocine moiety (racemic) or inserted in a bis-1,3-pyrazolophane skeleton (enantiopure) were investigated through N-15 NMR spectroscopy in natural abundance. Nitrogen chemical shifts were determined by (1D)-INEPT experiments, while proton-nitrogen scalar Coupling were obtained through 2D-J-HMBC experiments.
