## Abstract The synthesis of ^15^N‐labelled nornicotine **2** and ^15^N‐labelled nicotine **1** is described via the reductive aminocyclization of a 1,4‐ketoaldehyde with a corresponding amine in the presence of sodium cyanoborohydride. Yields of 30% and 26%, respectively, were obtained from 3‐brom

Abstract
Efficient syntheses of [^15^N~6~]‐labeled hexaaminobenzene (6), hexakis(dimethylamino)benzene (7) and 2,2′,2″‐trimethylbenzotris(imidazol) (1) are described. The compounds are characterized by ^15^N CPMAS NMR spectroscopy.

A new technique was developed for the large-scale synthesis of lSN-labelled urea at low enrichment levels. The synthesis is based on nucleophilic displacement of the phenoxide ion from phenyl carbonate and uses anhydrouli Pmmonia as the nucleophile. In previous reports a copper catalyst was used; ho
