## 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
Abstract
An improved synthesis of [^15^N] labelled acetamide and acetonitrile is described which provides these compounds in yields of 85% and 64%, respectively. The key difference in the present preparation is the use of 2,2,2‐trifluoroethyl acetate for the reaction with ^15^NH~4~OH.

## Abstract A continuous three‐step micro‐synthesis of 1,2‐dibromo‐3‐chloropropane, labelled with tritium in position 1 and 2, is described. A specific activity of 10.8 Ci/mmol is obtained. The yield observed in the uninterrupted overall synthesis is appreciably lower than that in the controlled st
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
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
## 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
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.
