DOI: 10.1002/cbic.201800758
Abstract: For the first time, a simple methodology for the chemical synthesis and use of highly reactive 4‐methylenoxazol‐5(4H)‐ones from serine is presented. These dehydroalanine derivatives, which resemble the natural 4‐methylidenimidazole‐5‐one (MIO) cofactor present in lyases and… read more here.

DOI: 10.1002/ijch.202000038
Abstract: The ferrocene titration method has been employed to determine the one-electron reduction potentials of a series of oxido-iron(IV), oxido-cobalt(IV) and oxido/hydroxido-nickel(III) complexes based on the same tetradentate TMG3tren ligand (TMG3tren= tris[2-(N-tetramethylguanidyl)ethyl] amine). The S=2 ground… read more here.
