## Abstract The synthesis of Asaley labelled with ^14^C in the mustard (Asaleyβmustβ^14^C) or the leucine (Asaleyβleuβ^14^C) moiety is described. In the former, ethyl paminoβN^Ξ±^βacetylβDLβphenylalanylβLβleucinate was reacted with ethylene oxide(U)β^14^C to give the bis(hydroxyethyl)amino analogue,
