title: tert-Butyl N-[(S)-3-isobutyl-2-oxooxetan-3-yl]carbamate.
abstract: The structure of the title compound, C(12)H(21)NO(4), contains two crystallographically independent mol-ecules in the asymmetric unit. Mol-ecules are linked into pseudosymmetric R(2) (2)(8) dimers through two N-H⋯O hydrogen bonds. The dimers are connected by weak C-H⋯O inter-actions, resulting in a three-dimensional network.
