of isotopically labelled L-leucine involving the preparation of 2-oxo-4-methylpentanoic acid labelledselectively with carbon-13 or deuterium in either the pro-R or pro-S methyl group followed by a reductive amination of the ketone catalysed by leucine dehydrogenase. This strategy is applied to the total synthesis of (2S.4R)-[5.5.5-D3]-leucine using CD3I as the source of deuterium.
