A PNA monomer containing thymine as nucleobase (1) was synthesized, characterized and coupled to the pyrazolyl containing ligand 3,5-Me2pz(CH2)2N((CH2)3COOH)(CH2)2NHBoc (2) and to a modified cysteine S-(carboxymethyl-pentafluorphenyl)-N-[(trifluor)ca

S-Alkylated cysteines are used as efficient tridentate N,O,S-donor-atom ligands for the fac-[M(CO)3]+ moiety (M=99mTc or Re). Reaction of (Et4N)2[ReBr3(CO)3] (3) with the model S-benzyl-L-cysteine (2) leads to the formation of [Re(2′)(CO)3] (4) as

Two different pathways for the introduction of an acetyl group at N(epsilon ) in a N(alpha), N(delta), and -COO protected histidine to afford N(epsilon)-(CH(2)COOH)-histidine derivative 7 b are presented. The purpose of this study is the coupling of

We have synthesized amino acids conjugated at the alpha-carbon through an alkyl spacer to a small tripod ligand. The tripod coordinates to the fac-[M(CO)3]+ moiety (M = Re, 99mTc). Depending on the lengths of the spacers, these metal complexes with p
