A new dibromination reaction involving the combination of dibromomalonate as the bromonium source and a titanium bromide species as the bromide source has been developed. Enantioselective catalysis has been achieved through apparent ligand acceleration by a tartaric acid-derived diol.

modification that develops novel functionalization approaches while shedding light on the development of selective chemistries in complex environments. Here, we elucidate the reaction parameters that allow selective catalysis and even discrimination among highly similar proteins. Furthermore, we show that quantifying modification allows the measurement of competitive ligand affinity, permitting straightforward
