title: tert-Butyl N-[(S)-3-isopropyl-2-oxo-oxetan-3-yl]carbamate.
abstract: The structure of the title compound, C(11)H(19)NO(4), contains two crystallographically independent mol-ecules in the asymmetric unit. Both adopt the same conformation and they form pseudosymmetric R(2) (2)(8) dimers via two N-H⋯O hydrogen bonds. The dimers are linked by weak C-H⋯O inter-actions and are stacked in columns along the a axis.
