A rapid isotopic labeling method for complex molecules containing a sulfur atom


​Researchers from SCBM, in collaboration with Paris-Sud University and INSA Toulouse, developed the first general method for tritium and deuterium labeling of complex molecules with thioether-type motifs (including sulfur atom). This method allows rapid access to tritiated or deuterated molecules used in the pharmaceutical industry for in vivo monitoring or the biological assay of substances of interest.

​Abstract

We present here the first example of C(sp3)–H activation directed by a sulfur atom. Based on this transformation catalyzed by Ru/C, we have developed a hydrogen isotope exchange reaction for the deuterium and tritium labelling of thioether substructures in complex molecules.
