broad-spectrum organoarsenical antibiotic, is a nonproteinogenic analogue of glutamate that effectively inhibits glutamine synthetase. We report the chemical synthesis of an intermediate in the pathway to 1, hydroxyarsinothricin [AST-OH (2)], which can be converted to 1 by enzymatic methylation catalyzed by the ArsM As(III) S-adenosylmethionine methyltransferase. This is the first report of semisynthesis
