Abstract

A scalable four-step synthesis of the ornithine transcarbamylase inhibitor N⁵-phosphonoacetyl-L-ornithine (PALO) is achieved through boroxazolidinone protection of ornithine. Investigations in the model organism Saccharomyces cerevisiae found that, in contrast to a previous report, PALO did not influence growth rate or expression of genes involved in arginine metabolism.
