Preparation of 2'-13c-l-histidine starting from 13c-thiocyanate: Synthetic access to any site-directed stable isotope enriched l-histidine

1-Benzyl-2-(methylthio)-imidazole-5-ketone is obtained in a few simple steps starting from thiocyanate and glycine amide (glycin). Subsequent treatment with diethyl phosphorocyanidate and functional group manipulations gives 1-benzyl-5-chloromethylimidazolium chloride. This compound is converted under mild O'Donnell conditions into the corresponding L-histidine derivative. After deprotection L-histidine is obtained in good yield and 99% enantiomeric excess. 2'-13C-L-Histidine has been obtained via this new scheme with high (99%) 13C incorporation starting with commercially available 13C- thiocyanate. This synthetic scheme allows access to any isotopomer of L-histidine and many other biologically important imidazole derivatives.
