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
