The tridentate cys–cys ligand was also employed as a scaffold for assembling the final bifunctional ligand incorporating the biotin bioactive group. The various reaction pathways employed for this synthesis are pictured in Fig. 8.3. (a) (b) (c) FIG. 8.3. Reaction diagram for the synthesis of the bifunctional ligand cys–cys biotin: (a) synthesis of allyl biotin, (b) synthesis of cys–cys alkyne and (c) Pauson–Khand cycloaddition to form the final cys–cys biotin. 124
Preliminary synthesis of the biotin allyl (see Fig. 8.3(a)) and cys–cys alkyne (see Fig. 8.3(b)) derivatives was needed to allow the final cys–cys biotinylated bifunctional ligand to be assembled through a Pauson–Khand cycloaddition reaction (see Fig. 8.3(c)) [8.15]. Although the final yield of preparation was
