چکیده انگلیسی
Novel 3-(2-naphthoyl)-6,12-diphenyl-3,9-diazatetraasterane (3, Tetraethyl 3-(2-naphthoyl)-6,12-diphenyl-3,9-diazapentacyclo [6.4.0.02,7.04,11.05,10]dodecane-1,5,7,11-tetracarboxylate) was prepared by naphthoylation of 3,9-diazatetraasterane (2). The target compound was isolated and unambiguously confirmed by NMR spectra, high-resolution mass spectrometry, and single-crystal X-ray diffraction analysis. In order to discuss the spatial effects on the NMR of 3 by the naphthoyl group, spectra analysis (1D-NMR and 2D-NMR) of 2 and 3 was conducted in details by the shifts and assignments of signals. Single-crystal X-ray diffraction assists to explain the molecular asymmetry of 3 and elucidates the effects of naphthoyl group on the geometry of the central cage of 3,9-diazatetraasterane.
