Abstract:
Five alkyne-containing hemoprotein models have been synthesized in a convergent manner. Sonogashira
coupling was used to introduce the alkyne functional group on the proximal imidazole before or after
being attached on the porphyrin. One model was immobilized onto a gold electrode surface via copper(I)-catalyzed azide-alkyne cycloaddition (Sharpless click chemistry).
