development of a new, high-yielding, scalable and safe process for the preparation of 2-aminoadamantane-2-carboxylicacid (1) is described. This geminal, functionalized achiral amino acid has been reported to possess interesting biological activity as a transport mediator due to its unique physiochemical properties. We report herein on the use of various mesoreactor flow devices to expedite the lab-scale
