and at least protected at the N
α
and optionally at the N
δ
; or derivatized at the N
α
and at least protected at the N
α
and optionally at the N
δ
; or derivatized at the N

and at least protected at the N
α
and optionally at the N
δ
; or derivatized at the N
ε
; or derivatized at the N
α
; or derivatized at the N

histidine to afford N(epsilon)-(CH(2)COOH)-histidine derivative 7 b are presented. The purpose of this study is the coupling of 7 b to amino groups in bioactive molecules such as peptides. After full deprotection of such a bioconjugate, histidine provides three coordination sites which efficiently coordinate to [(99m)Tc(OH(2))(3)(CO)(3)](+) or [Re(OH(2))(3)(CO)(3)](+) in a facial geometry. This allows the development
