5-tert-Butyl 1-ethyl 3-amino-1,4,5,6-tetrahydropyrrolo[3,4-c]pyrazole-1,5-dicarboxylate
The asymmetric unit of the title compound, C(13)H(20)N(4)O(4), contains two crystallographically independent mol-ecules in which the dihedral angles between the fused pyrrole and pyrazole rings are 5.06 (8) and 1.12 (8)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O and N-H⋯N hydrogen bonds into chains parallel to the b axis.

In the title compound, C(16)H(20)N(2)O(2), the pyrazole ring is essentially planar [maximum deviation = 0.008 (2) Å] and is inclined at an angle of 82.82 (10)° with respect to the phenyl ring. The crystal packing is consolidated by pairs of inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers stacked along the a axis.

In the title compound, C(13)H(16)N(4)O(2), the pyrazole ring forms a dihedral angle of 50.61 (6)° with the 3-nitro-phenyl ring. The plane of the nitro group is twisted by 6.8 (7)° out of the plane of the phenyl ring. In the crystal, the mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds, forming sheets in the bc plane. In addition, a weak C-H⋯N inter-action is observed.

In the title compound, C21H20ClNO6, the furan moiety is located above the mean plane of the indole ring and displays rotational disorder (i.e. rotation through 180°); the site occupancy of the major component is 0.809 (6). In the crystal, C-H⋯O inter-actions link the mol-ecules into chains which run parallel to the b axis.

In the title compound, C(17)H(27)N(3)O(4), the six-membered ring adopts a half-chair conformation with the N atom and the adjacent methyl-ene C atom displaced by -0.391 (2) and 0.358 (2) Å, respectively, from the plane of the other four atoms. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions.
