Tert-Butyl 4-(2-diazo-acet-yl)piperazine-1-carboxyl-ate.

ABSTRACT: The title crystal structure, C(11)H(18)N(4)O(3), is the first diazo-acetamide in which the diazo-acetyl group is attached to an N atom. The piperazine ring is in a chair form and hence the mol-ecule has an extended conformation. Both ring N atoms are bonded in an essentially planar configuration with the sum of the C-N-C angles being 359.8?(2) and 357.7?(2)°. In the crystal structure, the O atom of the diazo-acetyl group accepts two H atoms from C-H donors, thus generating chains of weak hydrogen-bonded R(2) (1)(7) rings.

(E)-tert-Butyl 4-(N'-hy-droxy-carbam--imid-o-yl)piperazine-1-carboxyl-ate.

Project description:In the title compound, C10H20N4O3, the piperazine ring adopts a chair conformation. The mol-ecule adopts an E conformation across the C=N double bond, with the -OH group and the piperazine ring trans to one another. Further, the H atom of the hy-droxy group is directed away from the NH2 group. An intra-molecular N-H⋯O contact occurs involving the NH2 group and the oxime O atom. In the crystal, mol-ecules are linked via strong N-H⋯O and O-H⋯N hydrogen bonds with alternating R2(2)(6) and C(9) motifs into tetra-meric units forming R4(4)(28) motifs.

1,4-Bis(2-diazo-acet-yl)piperazine.

Project description:The asymmetric unit of the title compound, C8H10N6O2, contains one-half mol-ecule, which is completed by a crystallographic center of symmetry. The piperazine ring adopts a chair conformation. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into layers parallel to the bc plane. The crystal packing also exhibits short N⋯N contacts of 3.0467 (16) Å between the terminal diazo N atoms from neighbouring mol-ecules.

tert-Butyl 4-{[2-amino-4-(2-hy-droxy-phen-yl)pyrimidin-5-yl]meth-yl}piperazine-1-carboxyl-ate.

Project description:In the title compound, C20H27N5O3, the central piperazine ring adopts a chair conformation, with the N-bound carboxyl-ate and methyl-ene substituents occupying bis-ectional and equatorial orientations, respectively. A twist is evident between the aromatic rings [dihedral angle = 25.61?(9)°] but an intra-molecular O-H?N hydrogen bond persists between these. Supra-molecular tapes along [1-10] are formed in the crystal packing through N(amino)-H?O(hydrox-yl) and N(amino)-H?N(pyrimidin-yl) hydrogen bonds, and these are linked into layers in the ab plane by ?-? inter-actions [inter-centroid distance between pyrimidinyl rings = 3.5919?(9)?Å].

tert-Butyl 4-{5-[3-(tri-fluoro-meth-oxy)phen-yl]-1,2,4-oxa-diazol-3-yl}piperazine-1-carboxyl-ate.

Project description:In the title compound, C18H21F3N4O4, the piperazine ring adopts a chair conformation and the dihedral angle between the oxa-diazole and benzene rings is 6.45?(14)°. The C atoms and their attached H atoms in the piperazine ring are disordered, with site-occupation factors of 0.576?(12) and 0.424?(12). In the crystal, mol-ecules are linked through weak C-H?O inter-actions, generating an R 2 (2)(12) motif. Further, secondary C-H?O inter-molecular inter-actions link the mol-ecules into C(6) chains along [100].

tert-Butyl 4-{[5-(4-chloro-phen-yl)-1-(4-fluoro-phen-yl)-1H-pyrazol-3-yl]carbon-yl}piperazine-1-carboxyl-ate.

Project description:In the title pyrazole derivative, C(25)H(26)ClFN(4)O(3), both benzene rings are twisted out of the plane through the pyrazole ring, with dihedral angles of 67.62 (10) and 27.63 (10)° for the fluoro- and chloro-substituted rings, respectively. The dihedral angle between the two benzene rings is 64.54 (9)°. The piperazine ring (with a chair conformation) is linked to the pyrazole ring via a carbonyl spacer and is orientated to lie to one side of the pyrazole plane. In addition to an intra-molecular C-H⋯N contact, there are inter-molecular C-H⋯O inter-actions, which generate a supra-molecular chain with an undulating topology along the c axis that is sustained by alternating centrosymmetric ten-membered {⋯HCNCO}(2) and {⋯HC3O}(2) synthons.

tert-Butyl imidazole-1-carboxyl-ate.

Project description:In the title compound, C(8)H(12)N(2)O(2), mol-ecules are inter-connected by weak C-H?O contacts with H?O distances of 2.30?Å, resulting in the formation of chains along [100]. According to graph-set analysis, the unitary descriptor of these chains is C(5). In addition, there are ?-? stacking inter-actions between pyrazole rings (centroid distance = 3.878?Å and ring plane distance = 3.26?Å).

Crystal structure of <i>tert</i>-butyl 4-[4-(4-fluoro-phen-yl)-2-methyl-but-3-yn-2-yl]piperazine-1-carboxyl-ate.

Project description:The title sterically congested piperazine derivative, C20H27FN2O2, was prepared using a modified Bruylants approach. A search of the Cambridge Structural Database identified 51 compounds possessing an N-tert-butyl piperazine substructure. Of these only 14 were asymmetrically substituted on the piperazine ring and none with a synthetically useful second nitro-gen. Given the novel chemistry generating a pharmacologically useful core, determination of the crystal structure for this compound was necessary. The piperazine ring is present in a chair conformation with di-equatorial substitution. Of the two N atoms, one is sp 3 hybridized while the other is sp 2 hybridized. Inter-molecular inter-actions resulting from the crystal packing patterns were investigated using Hirshfeld surface analysis and fingerprint analysis. Directional weak hydrogen-bond-like inter-actions (C-H⋯O) and C-H⋯π inter-actions with the dispersion inter-actions as the major source of attraction are present in the crystal packing.

Ethyl 1-tert-butyl-2-(4-methoxy-phen-yl)-1H-benzimidazole-5-carboxyl-ate.

Project description:In the title mol-ecule, C(21)H(24)N(2)O(3), the imidazole ring is essentially planar, with a maxium deviation of 0.015?(1)?Å. The dihedral angle between the benzene and imidazole rings is 65.47?(6)°. The crystal packing is stabilized by weak inter-molecular C-H?O and C-H?N hydrogen bonds, forming zigzag chains along the c axis. The crystal structure is further stabilized by C-H?? inter-actions.
