Popis: A convenient synthesis of carnosine-d7 and anserine-d4 is described. Coupling of N-Boc-β-alanine-d4 with L-histidine-d3 or 1-methyl-L-histidine using isobutyl chloroformate afforded the corresponding Boc-protected dipeptide. Subsequent Boc group deprotection with hydrochloric acid yielded carnosine-d7 and anserine-d4 in 46% and 69% overall yield, respectively.
