## 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
Double ^15^N‐labeled N‐nitropiperidine and N‐nitrodimethylamine have been conveniently prepared by oxidation of the corresponding nitrosamines. Dimethylamine‐^15^N was commercially available while the required piperidine‐^15^N was synthesized from cyclopentanone via the Schmidt ring‐expansion procedure using potassium azide‐1‐^15^N, followed by hydride reduction of the resulting 2‐piperidinone‐^15^N.

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
