Versatile control of the submolecular motion of di(acylamino)pyridine-based [2]rotaxanes.

ABSTRACT: A cyclic network of chemical reactions has been conceived for exchanging the dynamic behaviour of di(acylamino)pyridine-based rotaxanes and surrogates. X-ray diffraction studies revealed the intercomponent interactions in these interlocked compounds and were consistent with those found in solution by dynamic NMR experiments. This particular binding site was incorporated into a molecular shuttle enabled for accessing two states with an outstanding positional discrimination through chemical manipulation. Furthermore, the ability of the di(acylamino)pyridine domain to associate with external binders with a complementary array of HB donor and acceptor sites was exploited for the advance of an unprecedented electrochemical switch operating through a reversible anion radical recognition process.

A Versatile Axle for the Construction of Disassemblage Rotaxanes.

Project description:Rotaxanes are unique mechanical devices that hold great promise as sensors. We report on two new rotaxanes that contain an acid or base sensitive trigger and readily disassemble in a wide range of environments. Disassemblage was observed under TLC and ¹H-NMR analysis. The axle is highly charged, which enhances solubility in aqueous environments, and can be readily derivatized with sensor components. The trigger was swapped in a one-pot method, which is promising for the rapid production of a series of sensors.

Towards a RIOK2 chemical probe: cellular potency improvement of a selective 2-(acylamino)pyridine series.

Project description:RIOK2 is an understudied kinase associated with a variety of human cancers including non-small cell lung cancer and glioblastoma. No potent, selective, and cell-active chemical probe currently exists for RIOK2. Such a reagent would expedite re-search into the biological functions of RIOK2 and validate it as a therapeutic target. Herein, we describe the synthesis of naphthyl-pyridine based compounds that have improved cellular activity while maintaining selectivity for RIOK2. While our compounds do not represent RIOK2 chemical probes, they are the best available tool molecules to begin to characterize RIOK2 function in vitro.

Convenient syntheses of 2-acylamino-4-halothiazoles and acylated derivatives using a versatile Boc-intermediate.

Project description:The 2-aminothiazole grouping is a significant feature of many series of biologically active molecules, including antibiotics, anticancer agents and NSAIDs. We have a longstanding interest in the synthesis and biological evaluation of thiazolides, viz. [2-hydroxyaroyl-N-(thiazol-2-yl)-amides] which have broad spectrum antiinfective, especially antiviral, properties. However, 2-amino-4-substituted thiazoles, especially 4-halo examples, are not easily available. We now report practical, efficient syntheses of this class from readily available pseudothiohydantoin, or 2-aminothiazol-4(5H)-one: the key intermediate was its Boc derivative, from which, under Appel-related conditions, Br, Cl and I could all be introduced at C(4). Whereas 2-amino-4-Br/4-Cl thiazoles gave low yields of mixed products on acylation, including a bis-acyl product, further acylation of the Boc intermediates, with a final mild deprotection step, afforded the desired thiazolides cleanly and in good yields. In contrast, even mild hydrolysis of 2-acetamido-4-chlorothiazole led to decomposition with fast reversion to 2-aminothiazol-4(5H)-one. We also present a correction of a claimed synthesis of 2-acetamido-4-chlorothiazole, which in fact produces its 5-chloro isomer.

High yielding synthesis of 2,2'-bipyridine macrocycles, versatile intermediates in the synthesis of rotaxanes.

Project description:We present an operationally simple approach to 2,2'-bipyridine macrocycles. Our method uses simple starting materials to produce these previously hard to access rotaxane precursors in remarkable yields (typically >65%) across a range of scales (0.1-5 mmol). All of the macrocycles reported are efficiently converted (>90%) to rotaxanes under AT-CuAAC conditions. With the requisite macrocycles finally available in sufficient quantities, we further demonstrate their long term utility through the first gram-scale synthesis of an AT-CuAAC [2]rotaxane and extend this powerful methodology to produce novel Sauvage-type molecular shuttles.

6,6'-(Pyridine-2,6-di-yl)bis-(pyrrolo-[3,4-b]pyridine-5,7-dione).

Project description:The title compound, C(19)H(9)N(5)O(4), has crystallographically imposed twofold rotational symmetry. The asymmetric unit contains one half-mol-ecule. The crystal structure is stabilized by ?-? stacking of inversion-related pyrrolo-[3,4-b]pyridine rings, with a centroid-centroid distance between stacked pyridines of 3.6960?(8)?Å. The dihedral angle between the central pyridine ring and the pyrrolo-pyridine side rings is 77.86?(2)° while the angle between the two side chains is 60.87?(2)°.

N,N'-(Pyridine-2,6-di-yl)dibenzamide.

Project description:The mol-ecule of the title compound, C19H15N3O2, is completed by the application of crystallographic twofold symmetry, with the pyridine N atom lying on the rotation axis. The mol-ecular structure is approximately planar, the dihedral angle between the mean planes of the pyridine and benzene rings being 7.53?(11)°. In the crystal, N-H?O hydrogen bonds link the mol-ecules into a two-dimensional array perpendicular to the c axis.

1,1'-[4-(2,4-Dichloro-phen-yl)-2,6-di-methyl-1,4-di-hydro-pyridine-3,5-di-yl]diethanone.

Project description:In the title compound, C(17)H(17)Cl(2)NO(2), the central 1,4-dihydro-pyridine ring adopts a flattened-boat conformation. The ethanone substituents of the dihydro-pyridine ring at positions 3 and 5 have synperiplanar (cis) or anti-periplanar (trans) conformations with respect to the adjacent C=C bonds in the dihydro-pyridine ring. The 2,4-dichloro-phenyl ring is almost planar [r.m.s. deviation = 0.0045 (1) Å] and almost perpendicular [89.27 (3)°] to the mean plane of the dihydro-pyridine ring. In the crystal, an N-H⋯O hydrogen bond links mol-ecules into a zigzag chain along the ac diagonal. C-H⋯Cl contacts form centrosymmetric dimers and additional weak C-H⋯O contacts further consolidate the packing.

Poly[piperazinediium [[aqua-bismuth-ate(III)]-di-μ-pyridine-2,6-dicarboxyl-ato-bis-muthate(III)-di-μ-pyridine-2,6-dicarboxyl-ato] monohydrate].

Project description:The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which is eight-coordinate with a distorted bicapped trigonal-prismatic geometry, and another which is nine-coordinate with a distorted tricapped trigonal-prismatic geometry. The carboxyl-ate groups of the (pydc)(2-) ligands link dinuclear [Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)](2-) units into one-dimensional coordin-ation polymers. The pipzH(2) (2+) cations (site symmetry ) and non-coordinated water mol-ecules lie between these polymers, forming N-H⋯O and O-H⋯O hydrogen bonds to the O atoms of the carboxylate groups.

Calix[6]arene-based atropoisomeric pseudo[2]rotaxanes.

Project description:Some examples of atropoisomeric pseudorotaxanes in which the isomerism arises by the different conformations adopted by the wheel are reported here. Upon threading hexahexyloxycalix[6]arene 1 with ammonium axles 2+ or 3+ , bearing biphenyl or trifluoromethylbenzyl moieties, respectively, two atropoisomeric pseudorotaxanes were formed in which the calix[6]-wheel 1 adopts the 1,2,3-alternate and cone conformations. The interconversion between them cannot be obtained by simple rotation around the ArCH2Ar bonds of the calixarene wheel, which is blocked by the presence of the axle inside its cavity. Therefore, it can only be obtained through a mechanism of de-threading/re-threading of the axle. In all the examined cases, the 1,2,3-alternate and cone atropoisomers are, respectively, the kinetic and the thermodynamic ones.

Poly[(?3-5-tert-butyl-benzene-1,3-di-carboxyl-ato)di-pyridine-cobalt(II)].

Project description:In the title compound, [Co(C12H12O4)(C5H5N)2] n , the Co(II) cation is coordinated by four O atoms from three 5-tert-butyl-benzene-1,3-di-carboxyl-ate anions and two N atoms from pyridine mol-ecules in a distorted octa-hedral geometry. One carboxyl-ate group of the anionic ligand chelates a Co(II) cation while another carboxyl-ate group bridges two Co(II) cations, resulting in a polymeric layer parallel to (101). Weak C-H?O hydrogen bonds occur between adjacent polymeric layers. In the crystal, one of pyridine mol-ecules is equally disordered over two positions.
