Abstract: In the enantiomerically pure title compound, C₁₁H₁₉N₃O₃S, the chain C-N-C(O)-O-C-C (from the asymmetric carbon to a methyl of the tert-butyl group) displays an extended conformation. In the crystal, molecules are linked into chains parallel to the c axis by classical N-HO_{diazocarbonyl} hydrogen bonding and an unusual intermolecular three-centre interaction involving the amino acid (aa) carbonyl O_aa and the diazocarbonyl grouping C(O)-CH-NN, with HO_aa = 2.51 Å and NO_aa = 2.8141 (14) Å.
