Toward multifunctional anticancer therapeutics: Post-synthetic carbonate functionalization of asymmetric Au(I) bis-N-heterocyclic carbenes

A post-synthetic strategy is reported that allows for functionalization of Au(I)-Bis NHCs via carbonate formation. The scope of this methodology was explored using both aromatic and aliphatic alcohols. As a demonstration of potential utility, the fluorescent Au(I)-bis NHC conjugate 5 was prepared; i...

Description
Summary:A post-synthetic strategy is reported that allows for functionalization of Au(I)-Bis NHCs via carbonate formation. The scope of this methodology was explored using both aromatic and aliphatic alcohols. As a demonstration of potential utility, the fluorescent Au(I)-bis NHC conjugate 5 was prepared; it was found to have enhanced stability when formulated with bovine serum albumin, localise within the mitochondria of A549 cells and do so without compromising the high cytotoxicity seen for the parent Au(I)-Bis NHC system.
