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

ABSTRACT: 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.

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 π-π inter-actions [inter-centroid distance between pyrimidinyl rings = 3.5919 (9) Å].

tert-Butyl 1-hy-droxy-piperidine-2-carboxyl-ate.

Project description:The title compound, C(10)H(19)NO(3), is a disubstituted piperidine bearing substituents in two equatorial positions. One of the substituents is a hy-droxy group bound to nitro-gen and the second a tert-butyl ester group bound to the carbon next to the endocyclic nitro-gen. Enanti-omers of the title compound form hydrogen-bridged dimers across a center of inversion.

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

Project description: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.

Di-tert-butyl 1-[2-hy-droxy-3-(methyl-sulfan-yl)prop-yl]hydrazine-1,2-di-carboxyl-ate.

Project description:The title compound, C14H28N2O5S, was synthesized by the reaction of 2-[(methyl-sulfan-yl)meth-yl]oxirane with di-tert-butyl oxalate in hydrazine hydrate. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds into supra-molecular chains propagating along the b-axis direction.

tert-Butyl 2-{[2,8-bis-(trifluoro-meth-yl)quinolin-4-yl](hy-droxy)meth-yl}piperidine-1-carboxyl-ate.

Project description:The title mol-ecule, C(22)H(24)F(6)N(2)O(3), adopts a folded conformation whereby the carboxyl-ate residue lies over the quinolinyl residue, with the dihedral angle between the carbamate and quinoline planes being 41.64 (7)°. Helical supra-molecular C(7) chains sustained by O-H⋯O hydrogen bonds propagating along the a-axis direction feature in the crystal packing. The F atoms of one of the CF(3) groups are disordered over two orientations; the major component has a site occupancy of 0.824 (7).

Methyl 2-[(3,5-di-tert-butyl-4-hy-droxy-benz-yl)sulfan-yl]pyridine-3-carboxyl-ate n-hexane hemisolvate.

Project description:The title solvated ester, C(22)H(29)NO(3)S·0.5C(6)H(14), crystallizes with two independent mol-ecules along with a hexane mol-ecule in the asymmetric unit. The two aromatic rings are separated by an -CH(2)-S- linkage; the rings are aligned at 83.27?(4)° in one mol-ecule and 47.66?(7)° in the other. The hy-droxy group of one mol-ecule forms an O-H?O hydrogen bond to the other mol-ecule.

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.
