Structural study of ethyl 3-arylcarbamoyl-2,3-diazabicyclo[2.2.1]hept-5-ene-2-carboxylates: conformation and transmission of substituent effects across the diazabicycloheptene ring

Nine new ethyl 3‐arylcarbamoyl‐2,3‐diazabicyclo[2.2.1]hept‐5‐ene‐2‐carboxylates were prepared by a [4 + 2] cycloaddition and their FTIR, 1H, 13C and 15N NMR spectra were measured and assigned. Single crystals were grown for five compounds and their X‐ray data were obtained. The electronic structure...
