The present invention concerns a novel method for synthesising diazirines, that may or may not be enriched in nitro-gen-15, from amino acids or imines, via a one-pot synthesis method, comprising the reaction of the starting amino acid or imine with ammonia, which may or may not be enriched in nitrogen-15, and a hypervalent iodine oxidant. The present invention also relates to a method for synthesising ammonia enriched in nitrogen-15. The invention also concerns certain diazirines of formula (I) likely to be obtained by the claimed synthesis method, and also refers to the

-diazirines of formula (I′). The claimed diazirines can be used in photoaffinity labelling. The
