## 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

✦ Synopsis
The synthesis of 15N labelled nylon 6 by anionic polymerization of Ecaprolactam is described. Labelling of this commercially important polymer should greatly enhance investigations of its morphology by techniques such as NMR, IR, and Raman spectroscopies.

## Abstract The ifosfamide metabolite isophosphoramide mustard (IPM) was synthesized with isotopic enrichment at each nitrogen site. Glycine‐^15^__N__ was converted to 2‐chloroethylamine‐^15^__N__ hydrochloride (4 steps, 21% net yield) which was then reacted with phenyl dichlorophosphate to provide
## Abstract We report the synthesis of [6‐^15^N]‐labeled‐AMP following a novel route from adenosine with an overall yield (12%) better than with a previously described procedure from inosine (6%). The two analogues of [6‐^15^N]‐adenosine triphosphate, adenylyl imidodiphosphate (AMP‐PNP) and adenyly
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
## Abstract A five‐step synthesis of the neonicotinoid insecticide imidacloprid (**1**) labelled with ^15^N is reported in an overall yield of 10%. The stable isotope ^15^N was introduced in the pyridine part by reaction of ^15^NH~3~ with coumalic acid methyl ester (**2**) to ^15^__N__‐hydroxy nico
5-Nitro-2,4-dihydro-3H-l,2,4-triazol-3-one (NTO) has been synthesized in good yield with 15N at the 1 and 2 positions. The N-H coupling provides unequivocal assignments for I H and 15N NMR spectra and the acidic proton. The products of thermal decomposition at 270 O C were identified spectroscopical
