Abstract

^15^N labeled tetranitromethane, C(^15^NO~2~)~4~, was prepared from anhydrous nitric acid and acetic anhydride. A procedure for the preparation of the nitric acid from Na^15^NO~3~ is described. Tyrosine was nitrated with H^15^NO~3~ and its ^15^N NMR spectrum compared well with that of tyrosine nitrated with C(^15^NO~2~)~4~.

Buspirone 1 is a novel, clinically effective anxiolytic agent which is devoid of the sedative, anticonvulsant or muscle relaxant properties normally associated with the benzodiazepines. Buspirone labelled with both radioactive (14C) and stable (15N) isotopes was required in order to investigate the

## Abstract ^15^N n.m.r. spectra of [^13^C‐2, 3‐^15^N~2~‐__guanidino__]arginine and [^13^C, ^15^N~2~] urea were obtained in D~2~O and H~2~O at a variety of pH values both with and without proton decoupling. The effects of the proton exchange rate are readily observable in the proton coupled ^15^N s

## Abstract Two types of multi‐labelled urocanic acids with stable isotopes, __i.e.__, [3‐^2^H,1β€²,3′‐^15^N~2~]urocanic acid and [2,3,5′‐^2^H~3~,2′‐^13^C,1β€²,3′‐^15^N~2~]urocanic acid were synthesized by the enzymatic reaction of DL‐[3,3‐^2^H~2~,1β€²,3′‐^15^N~2~]histidine or DL‐[2,3,3,5′‐^2^H~4~,2′‐^13
