Abstract

Analysis of the ^13^C NMR spectra of a series of 2,3‐dihydro‐1__H__‐pyrrolo[1,2‐c]imidazole derivatives has provided chemical shift data for (˜184 ppm), (˜173.5 ppm), (˜158 ppm) and (˜148 ppm) groups. A full analysis of the ^13^C chemical shifts of the C atoms of the pyrrole ring and of an N‐phenyl substituent is described.

## Abstract The ^1^H and ^13^C NMR data for 3‐azabicyclo[3.3.1]nonanes with OH and OMe substituents at C‐6 and C‐9 were measured using 1D (DEPT) and 2D (COSY, HSQC, HMBC, NOESY) experiments. Comparison of this NMR data illustrates the effects of stereochemistry and substitution at these positions.

1-Aryl-4-carboxy-5-methyl-1,2,3-triazoles were prepared by the condensation of aryl azides with ethyl acetoacetate. The structures of these compounds were characterized by MS, IR and 1H and 13C NMR spectroscopy. The measured and calculated 13C chemical shifts of the aromatic carbons were compared.
