catalysed reactions (Candida cylindracea lipase to hydroluse the ester and leucine dehydrogenase to catalyse the reductive amination of the ketone). This strategy may be simply adapted for the selective labelling of each site of the L-amino acid.

Approaches are described to the synthesis of a series of isotopicallylabelled L-α-amino acids each with an asymmetric centre at C-3, including isoleucine, allo-isoleucine, threonine and allo-threonine. The methods may be simply adapted for the selective incorporation of an isotopiclabel at each site of L-valine including the selective labelling of either diastereotopic methyl group with carbon-13
