Several 6-methyl-9-carbamoyltetrahydro-4H-pyrido[l,2-a]pyrimid~-4-ones have been prepared using phosgene iminium chloride. These compounds can exist in equilibrium as the cis (3A) imine$(3B) enaminee trans (3C) imine. 'H, 13C and "N NMR prove that the cis-and trans-imine isomers are predominant in t

Unambiguous 1H and 13C chemical shift assignments of the novel antibiotic 6,7,8,9-tetrahydro-7,7dimethyl-dioxolo [5,4-b]acridin-9-one were made using the FUCOUP pulse sequence. The appropriate phase cycling was calculated using the Compact Cartesian Coordinate Product Operator (C3PO) method. Copyrig
## Abstract The molecular structures of the title compounds 3 and 5 were investigated by NMR and X‐ray structural methods. The NMR results suggest two equivalent halves for both molecules. The X‐ray study shows an approximate mirror plane for 3 and an approximate twofold axis for a significant port
## Abstract The ^1^H and ^13^C NMR spectra of 4,8,9,10‐tetraaryl‐1,3‐diazatricyclo[3.3.1.13, 7]decan‐6‐ones were measured at 400 and 500 and at 100 and 125 MHz, respectively. The chemical shifts were assigned unambiguously using one‐ and two‐dimensional (H,H‐COSY, C,H‐COSY, NOESY, ROESY and HMBC) N
