In this project, we propose to develop an industrially scalable, practical method for the synthesis of a-arylated quaternary amino acids in enantiomerically pure form by streamlining, optimization and scale-up of a reaction we discovered while working on the synthesis of quaternary amino acids as conformational controllers within an ERC-funded Advanced Grant.
