Abstract

In the enanti-omerically pure title compound, C(11)H(19)N(3)O(3)S, 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, mol-ecules are linked into chains parallel to the c axis by classical N-H⋯O(diazo-carbon-yl) hydrogen bonding and an unusual inter-molecular three-centre inter-action involving the amino acid (aa) carbonyl O(aa) and the diazo-carbonyl grouping C(O)-CH-N N, with H⋯O(aa) = 2.51 Å and N⋯O(aa) = 2.8141 (14) Å.
