چکیده
In the crystal of the title compound, C(14)H(15)NO(4), pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular C-H⋯O hydrogen bonds, forming a three-dimensional network. The heterocyclic ring adopts a twisted conformation.

In the title compound, C(16)H(17)NO(5), the six-membered N-containing ring has a half-boat form; the spiro C atom deviates by 0.34 (2) Å from the plane (r.m.s. deviation = 0.051 Å) defined by the N and four aromatic C atoms. Intra-molecular N-H⋯O hydrogen bonding generates an S(6) ring motif and the dihedral angle between the mean plane though the S(6) ring and that through the five-atom half-b...

In the title mol-ecule, C(13)H(19)NO(4), except for two C atoms of the tert-butyl group, the non-H atoms are almost coplanar (r.m.s. deviation = 0.2542 Å). In the crystal, mol-ecules are linked into centrosymmetric dimers by two inter-molecular N-H⋯O hydrogen bonds, forming an R(2) (2)(10) ring motif.
