Abstract
This report presents an efficient syntheses of two labelled internal standards [^15^N~3~]melamine and [^13^C~3~]cyanuric acid with the common substrates [^15^N]NH~4~Cl and [^13^C]urea, respectively. Both standards with excellent isotopic and chemical purities were prepared in good yields and could be used as internal standards without further purification.

## Abstract 5β[4β^13^C,^15^N]β and 5β[5β^13^C,^15^N]Aminolevulinic acid (ALA) were simply synthesized in four steps by the condensation of [1β^13^C,^15^N]β or [2β^13^C,^15^N]glycine, respectively, with phthalic anhydride, followed by conversion to the chloride, coupling reaction with a threeβcarbon
A synthesis of the title compound from /13Clparaformaldehyde and [15N)ammonium chloride V f 8 ethyl 2-(1 ,3-/2-13Cldithianyl) acetate 3a is described. Ethyl/3-13C13-oxopropanoate derived in sl'tu from 3a was converted by a stepwise Strecker procedure to DL-[ 2-13C,15Nlaspartic acid 7a.
