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.
在对映体纯的标题化合物C₁₁H₁₉N₃O₃S中，链C-N-C(O)-O-C-C（从不对称碳原子到叔丁基的一个甲基）呈伸展构象。在晶体中，分子通过经典的N-H⋯O（重氮羰基）氢键和一种不寻常的分子间三中心相互作用连接成平行于c轴的链，该相互作用涉及氨基酸（aa）羰基O(aa)和重氮羰基基团C(O)-CH-N=N，其中H⋯O(aa) = 2.51 Å，N⋯O(aa) = 2.8141 (14) Å。
