Enantioselective Synthesis of Axially Chiral Biaryls via Copper-Catalyzed Thiolation of Cyclic Diaryliodonium Salts

Here, we report a chiral copper(II)-bisoxazoline-catalyzed enantioselective ring opening of cyclic diaryliodonium salts with heteroaryl thiols. The readily available 2-mercaptobenzoxazole and 2-mercaptobenzothiazole derivatives reacted efficiently with cyclic diaryliodonium salts and afforded various axially chiral biaryls bearing iodine and sulfur functional groups in excellent yields and enantioselectivities. The products were further transformed into diverse enantiopure alkyl biaryl sulfides, which can be employed as chiral ligands.

Microwave-assisted synthesis of new imide-and formamide-derivatives of 2(3H)-benzoxazolinones and 2(3H)-benzothiazolinones

With the aim to obtain 2(3H)-benzoxazolinones and 2(3H)-benzothiazolinone derivatives, we synthesized new imide compounds 5a-c, 6c-d and 7a-d by treating their 6-amino precursors with succinic, maleic or phthalic anhydride. The microwave (MW)-assisted reaction provided them more efficiently than through the corresponding isolated amic acids. The same nucleophile reagents were used in a MW-assisted formylation to obtain new formamide products 8-11, that were detected as cis/trans forms by NMR analysis. The ratio was in favor of the cis isomer and affected by the solvent, as also supported by DFT calculations.

Studies on nonlinear optical polyurethanes containing heterocyclic chromophores

This paper presents the synthesis of highly stable nitro-substituted thiazole, benzothiazole and thiadiazole chromophores. With these, a series of second-order nonlinear optical (NLO) responsive polyurethanes were successfully synthesized from tolylene-2,4-diisocyanate (TDI) and 4,4?- methylenedi(phenyl isocyanate) (MDI). Molecular structural characterization of these polyurethanes was achieved by 1H NMR, FT-IR, GPC and analytical data. The weight-average molecular weights (Mw) of the resulting polyurethanes were determined by GPC and ranged between 22,100 and 26,700. All the polyurethanes were highly soluble in aprotic solvents such as tetrahydrofuran, cyclohexanone, N,N-dimethylformamide, N,N-dimethylacetamide, dimethylsulphoxide, N-methyl-2-pyrolidinone, etc. The thermal behaviour of these polyurethanes was investigated using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Their glass transition temperatures were in the range 140-165 C and most of the polymers showed high thermal stability. With an in situ poling and temperature ramping technique, the optimal temperatures (Topts) for corona poling were determined for the largest second-order NLO response. The second harmonic generation (SHG) coefficients (d33) of the poled polyurethane films range from 62.21 to 103.11 pm/V at 1064 nm. All the poled films showed outstanding orientational stability up to 120 C without any measurable decay in the SHG signal. Of these, the polyurethane with nitro-substituted benzothiazole moiety (IIb) showed the best dynamical thermal stability of the poling-induced dipole alignment up to ?150 C.

Discovery of selective aminothiazole aurora kinase inhibitors.

Aurora family kinases regulate important events during mitosis including centrosome maturation and separation, mitotic spindle assembly, and chromosome segregation. Misregulation of Aurora kinases due to genetic amplification and protein overexpression results in aneuploidy and may contribute to tumorigenesis. Here we report the discovery of new small molecule aminothiazole inhibitors of Aurora kinases with exceptional kinase selectivity and report a 1.7 A cocrystal structure with the Aurora B:INCENP complex from Xenopus laevis. The compounds recapitulate the hallmarks of Aurora kinase inhibition, including decreased histone H3 serine 10 phosphorylation, failure to complete cytokinesis, and endoreduplication.

Synthesis and evaluation of an Iejimalide-archazolid chimera

Even though the macrolides of the iejimalide family are of marine origin, whereas those of the archazolid series derive from terrestrial myxobacteria, a comparison of their constitution, stereochemistry, and biological activity suggests that these natural products are close structural and functional relatives. Guided by this perception, compound 5 was prepared, which hybridizes the macrolactone core of iejimalide B (2) with the tail of archazolid A (3). The cytotoxicity profile of this chimera, as determined with a panel of 12 human cancer cell lines, corresponds to that of the parent compound 2, although its potency is lower. This outcome may be interpreted on the basis of molecular dynamics calculations, which suggest that the low energy conformations of 2 and 5 are similar but the energetic barriers between the relevant conformers are distinctly higher for the hybrid structure. The synthesis of 5 hinged on a regioselective functionalization of 2,4-dibromothiazole 6, a highly selective CBS-reduction of ketone 8, a Suzuki cross coupling of vinyl boronate 17 with the elaborate alkenyl iodide 16, and a productive closure of the macrocycle by RCM, which requires the selective activation of two out of eight double bonds present in the cyclization precursor 20 by the second-generation Grubbs catalyst 21.

Design, synthesis and evaluation of N-(substituted benzothiazol-2-yl)amides as anticonvulsant and neuroprotective

A series of N-(substituted benzothiazol-2-yl)amide derivatives 2a-h and 4a-h were synthesized by the EDC coupling reactions of substituted-benzothiazol- 2-amine with 4-oxo-4-phenylbutanoic acid/2-benzoyl benzoic acid and evaluated for their anticonvulsant and neuroprotective effect. N-(6-methoxybenzothiazol-2- yl)-4-oxo-4-phenylbutanamide (2f) emerged as the most effective anticonvulsant with median doses of 40.96 mg/kg (MES ED50), 85.16 mg/kg (scPTZ ED50) and 347.6 mg/kg (TD50). Furthermore, compound 2f displayed promising neuroprotective effect by lowering the levels of MDA and LDH; therefore, it represents a potential lead in search for safer and effective anticonvulsants having neuroprotective effects.

Microwave-assisted synthesis of novel N-(4-phenylthiazol-2-yl)-benzo[d]thiazole-, thiazolo[4,5-b]pyridine-, thiazolo[5,4-b]pyridine- and benzo[d]oxazole-2-carboximidamides inspired by marine topsentines and nortopsentines

We report the synthesis of novel N-(4-phenylthiazol-2-yl)-substituted benzo[d]thiazole-, thiazolo[4,5-b]pyridine-, thiazolo[5,4-b]pyridine- and benzo[d]oxazole-2-carboximidamides, which were inspired by marine topsentines and nortopsentines. Condensation of 4,5-dichloro-1,2,3-dithiazolium chloride (Appel salt) with various ortho-halogenated anilines, aminopyridines and aminophenols gave the corresponding aryliminodithiazoles in good to excellent yields. Copper(I)-mediated or nucleophilic-assisted cyclization of aryliminodithiazoles furnished cyano-functionalized benzo[d]thiazoles, thiazolo[4,5-b]- and thiazolo[5,4-b]-pyridines and benzo[d]oxazoles. The latter were condensed with substituted 4-phenylthiazol-2-amines to furnish twenty seven new polyaromatic carboximidamides in moderate to good yields.

Selective NR1/2B N-methyl-D-aspartate receptor antagonists among indole-2-carboxamides and benzimidazole-2-carboxamides

(4-Benzylpiperidine-1-yl)-(6-hydroxy-1H-indole-2-yl)-methanone (6a) derived from (E)-1 -(4-benzylpiperidin-1-yl)-3-(4-hydroxy-phenyl)-propenone (5) was identified as a potent NR2B subunit-selective antagonist of the NMDA receptor. To establish the structure-activity relationship (SAR) and to attempt the improvement of the ADME properties of the lead, a series of compounds were prepared and tested. Several derivatives showed low nanomolar activity both in the binding and in the functional assay. In a formalin-induced hyperalgesia model in mice, 6a and (4-benzylpiperidine-1-yl)-[5(6)-hydroxy-1H-benzimidazol-2- yl]-methanone (60a) were as active as besonprodil (2) after oral administration. A CoMS1A model was developed based on binding data of a series of indole- and benzimidazole-2-carboxamides.
