Process Development and Good Manufacturing Practice Production of a Tyrosinase Inhibitor via Titanium-Mediated Coupling between Unprotected Resorcinols and Ketones
economically attractive process for the synthesis of a novel tyrosinase inhibitor has been developed and implemented on a multikilogram scale under GMP. A major achievement to the success of the process is the development of a direct coupling between free resorcinol and ketone. First developed under basic conditions, this coupling has been turned to a novel titanium(IV) mediated process allowing good selectivity
