Atropisomeric 8-arylchromen-4-ones exhibit enantioselective inhibition of the DNA-dependent protein kinase (DNA-PK)

Substitution at the 3-position of the dibenzothiophen-4-yl ring of 8-(dibenzo[b,d]thiophen-4-yl)-2-morpholino-4H-chromen-4-one NU7441, a potent and selective DNA-dependent protein kinase (DNA-PK) inhibitor, with propyl, allyl or methyl enabled the separation by chiral HPLC of atropisomers. This is a consequence of restricted rotation about the dibenzothiophene-chromenone bond. Biological evaluation against DNA-PK of the pairs of atropisomers showed a marked difference in potency, with only one enantiomer being biologically active.

Palladium(II)/N,N-disubstituted-N?-acylthioureas complexes as anti-Mycobacterium tuberculosis and anti-Trypanosoma cruzi agents

The new complexes of Pd(II) with N,N-disubstituted-N?-acylthioureas:[(1) [Pd(dppf)(N,N-dimethyl-N?-benzoylthioureato-k2O,S)]PF6, (2) [Pd(dppf)(N,N-diethyl-N?-benzoylthioureato-k2O,S)]PF6, (3) [Pd(dppf)(N,N-dibuthyl-N?-benzoylthioureato-k2O,S)]PF6, (4) [Pd(dppf)(N,N-diphenyl-N?-benzoylthioureato-k2O,S)]PF6, (5) [Pd(dppf)(N,N-diethyl-N?-furoylthioureato-k2O,S)]PF6, (6) [Pd(dppf)(N,N-diphenyl-N?-furoylthioureato-k2O,S)]PF6, (7) [Pd(dppf)(N,N-dimethyl-N?- thiophenylthioureato-k2O,S)]PF6, and (8) [Pd(dppf)(N,N-diphenyl-N?-thiophenylthioureato-k2O,S)]PF6, were prepared and characterized by elemental analysis, and spectroscopic techniques. The structures of complexes (2), (3), (5), (6) and (8) had their structures determined by X-ray crystallography, confirming the coordination of the ligands with the metal through sulfur and oxygen atoms, forming distorted square-planar geometries. These complexes have shown antibacterial activity against anti-Mycobacterium tuberculosis H37Rv ATCC 27294. The complexes exhibited antiparasitic activity against Trypanosoma cruzi, while the metal-free thioureas did not. The results demonstrated that the compounds described here can be considered as promising anti-Mycobacterium tuberculosis and anti-T. cruzi agents, since in both cases their in vitro activity were better than reference drugs available for the treatment of both diseases.

Multimetallic complexes of group 10 and 11 metals based on polydentate dithiocarbamate ligands

The ligands KS2CN(Bz)CH2CH2N(Bz)CS 2K (K2L1), N(CH2CH 2N(Me)CS2Na)3 (Na3L2), and the new chelates {(CH2CH2)NCS2Na} 3 (Na3L3) and {CH2CH 2N(CS2Na)CH2CH2CH 2NCS2Na}2 (Na4L4), react with the gold(I) complexes [ClAu(PR3)] (R = Me, Ph, Cy) and [ClAu(IDip)] to yield di-, tri-and tetragold compounds. Larger metal units can also be coordinated by the longer, flexible linker, K2L1. Thus two equivalents of cis-[PtCl2(PEt3)2] react with K2L1 in the presence of NH4PF 6 to yield the bimetallic complex [L1{Pt(PEt 3)2}2](PF6)2. The compounds [NiCl2(dppp)] and [MCl2(dppf)] (M = Ni, Pd, Pt; dppp = 1,3-bis(diphenylphosphino)propane, dppf = 1,1′-bis(diphenylphosphino) ferrocene) also yield the dications, [L1{Ni(dppp)}2] 2+ and [L1{Ni(dppf)}2]2+ in an analogous fashion. In the same manner, reaction between [(L?2) (AuCl)2] (L?2 = dppm, dppf; dppm = bis(diphenylphosphino)methane) and KS2CN(Bz)CH2CH 2N(Bz)CS2K yield [L1{Au2(L? 2)}2].

Carbonylation of aryl halides: Extending the scope of the reaction

Carbonylation reactions are being increasingly favoured in pharmaceutical chemistry for the atom-efficient introduction of carbonyl centres in aldehydes, acids, esters, and amides. Convenient procedures for simple aryl iodides and bromides are well established, and now the need is to develop improved conditions to allow the reactions to be extended to the more unreactive substrates, such as sterically hindered compounds and aryl chlorides. Sterically hindered compounds such as 2-iodo- or 2-bromo-m-xylenes can be converted using alkoxy and aminocarbonylation, while dehalogenation becomes a significant side reaction for reductive carbonylation. Less hindered compounds such as 2-iodo- or bromotoluene can be reacted successfully. Changing the aryl ligands of PdCl2{Ph2P(CH2)3PPh2} to alkyl groups improves the rate of oxidative addition but slows the carbonyl insertion step such that rates for the majority of aryl bromides are not improved by this change. Complexes such as PdCl2{Cy 2P(CH2)3PCy2} offer better performance for alkoxy and aminocarbonylation of aryl chlorides. However, for reductive carbonylation dehalogenation is a significant side reaction. Increasing CO pressure results in additional CO coordination to the catalytic intermediates and slows the reaction, while the dehalogenation is little affected, so reaction selectivity suffers. Thus, CO pressure is a critical parameter, particularly for reductive carbonylation, in achieving the optimum performance.

Synthesis and properties of conjugated copolymer having alternate structure of diphenylanthracene and allene

A conjugated copolymer having an alternate structure of 9,10-diphenylanthracene and 1,3-diphenylallene was synthesized by the Suzuki-Miyaura cross-coupling reaction with 9,10-dibororanylanthracene and 1,3-bis(4-bromophenyl)-1,3-diphenylallene. The diphenylanthracene moiety worked as an absorptive and emissive center unit in the polymer. The twisted allene moiety not only controlled conjugation length of the polymer but also suppressed formation of excimers, which realized intense pure blue fluorescence with high quantum efficiency (Phif ? 1.0) in CHCl3 solution.

Formal Ir-Catalyzed Ligand-Enabled Ortho and Meta Borylation of Aromatic Aldehydes via in Situ-Generated Imines

The ligand-enabled development of ortho and meta C-H borylation of aromatic aldehydes is reported. It was envisaged that while ortho borylation could be achieved using tert-butylamine as the traceless protecting/directing group, meta borylation proceeds via an electrostatic interaction and a secondary interaction between the ligand of the catalyst and the substrate. These ligand-substrate electrostatic interactions and secondary B-N interactions provide an unprecedented controlling factor for meta-selective C-H activation/borylation.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C35H32Cl4FeP2Pd, you can also check out more blogs about95464-05-4

Developing an ionic medium for ligandless-palladium-catalysed Suzuki and Heck couplings

High-melting-point alkylammonium tetrafluoroborates melt with water or toluene to form biphasic mixtures at much lower temperatures than their normal melting points, thus could serve as green reaction media for Suzuki and Heck couplings. Advantages of using the aqueous-ammonium biphasic catalytic system include: (1) working well with a ligandless palladium catalyst, (2) solving the solubility problem of organic substrates and (3) simplifying work-up procedures for both separation of products and recycling of reaction media.

Total Synthesis of Lycoricidine and Narciclasine by Chemical Dearomatization of Bromobenzene

The total synthesis of lycoricidine and narciclasine is enabled by an arenophile-mediated dearomative dihydroxylation of bromobenzene. Subsequent transpositive Suzuki coupling and cycloreversion deliver a key biaryl dihydrodiol intermediate, which is rapidly converted into lycoricidine through site-selective syn-1,4-hydroxyamination and deprotection. The total synthesis of narciclasine is accomplished by the late-stage, amide-directed C?H hydroxylation of a lycoricidine intermediate. Moreover, the general applicability of this strategy to access dihydroxylated biphenyls is demonstrated with several examples.

Selective oxidative carbonylation of amines to oxamides and ureas catalyzed by palladium complexes

A new process for converting secondary amines into N,N,N?,N?- tetraalkyloxamides under CO pressure, catalyzed by homogeneous palladium complexes in the presence of 1,4-dichloro-2-butene (DCB) as an oxidant, has been developed. The mechanism of the oxidative double-carbonylation process, consisting of the oxidation of Pd(0) to Pd(11) with DCB through a beta-chloride elimination of the eta3-(chloromethyl) allylpalladiuni(11) intermediate, the formation of mono- and bis(carbamoyl)palladium species, and a reductive elimination of the two carbamoyl ligands, is proposed based on studies of the behavior of carbamoylpalladium complexes. When primary amines are employed with DCB as the oxidant, N,N?-dialkyloxamide is catalytically produced, whereas urea is exclusively produced when iodine is used as the oxidant. The reaction of an N-monopropylcarbamoylpalladium complex with propylamine under CO gave N,N?-dipropylurea, whereas a treatment with diethylamine yielded unsymmetrical N,N-diethyl-N?-propylurea, implying the intermediate formation of propyl isocyanate that is converted into the urea upon a reaction with the added amine. A kinetic study on the reaction of chloro-N- propylcarbamoylpalladium with triethylamine suggested a process proceeding through a base-promoted dcprolonalion of the N-monoalkylcarbamoyl ligand to form propyl isocyanate.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.
