Ferrocene‐amino acid ester‐uracil conjugates, derived from four amino acids (l‐alanine, glycine, β‐alanine and γ‐aminobutyric acid), were synthesized via the Cu(I)‐catalyzed azide‐alkyne cycloaddition as the key step. The new compounds were characterized spectroscopically and by single‐crystal X‐ray crystallography in the case of the derivatives of glycine (monoclinic, P21/c) and γ‐aminobutyric acid (orthorhombic, Pca21). Electrochemical measurements showed subtle influence of the compounds’ structure on the redox potential of the Fc/Fc+ couple. Among the four compounds tested for antimicrobial activity, the conjugate obtained from l‐alanine possessed weak antifungal activity against Candida guillermondii.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
