Author is Tan, Bryan Yong-Hao; Teo, Yong-Chua.

A convenient protocol for the C-N cross-coupling of aliphatic amides and iodobenzene is demonstrated using a simple and inexpensive Co(C2O4)·2H2O/N,N’-dimethylethylenediamine (DMEDA) catalytic system in water. Good yields of N-arylated products I [R1 = Pr, i-Pr, Bu, etc; R2 = Ph, 2-F-C6H4, 4-Me-C6H4, etc.] were isolated (up to 85%) and the protocol has been successfully applied to the synthesis of the anticancer drug, flutamide.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3-Bromo-4-chloronitrobenzene, is researched, Molecular C6H3BrClNO2, CAS is 16588-26-4, about 4-Substituted 1-Chloro-2-nitrobenzenes: Structure-Activity Relationships and Extension of the Substrate Model of Rat Glutathione S-Transferase 4-4.SDS of cas: 16588-26-4.

In the present study, eleven 4-substituted 1-chloro-2-nitrobenzenes were tested for their GSH conjugation capacity when catalyzed by base or rat glutathione S-transferase (GST) 4-4. Kinetic parameters (ks and Km, kcat, and kcat/Km) were determined and subsequently used for the description of structure-activity relationships (SAR’s). For this purpose, eight physicochem. parameters (electronic, steric, and lipophilic) of the substituents and five computer-calculated parameters of the substrates (charge distributions and several energy values) were used in regression analyses with the kinetic parameters. The obtained SAR’s are compared with corresponding SAR’s for the GSH conjugation of 2-substituted 1-chloro-4-nitrobenzenes, previously determined [van der Aar et al. (1996) Chem. Res. Toxicol. 9, 527-534]. The kinetic parameters of the 4-substituted 1-chloro-2-nitrobenzenes correlated well with the Hammett σp- constant: the Hammett σp constant corrected for “”through resonance”” while the corresponding kinetic parameters of the 2-substituted 1-chloro-4-nitrobenzenes did not. The base- and GST 4-4-catalyzed GSH conjugation reactions of 2-substituted 1-chloro-4-nitrobenzenes depend to a different extent on the electronic properties of the ortho substituents, suggesting the involvement of different rate-limiting transition states. The base- and GST 4-4-catalyzed conjugation of 4-substituted 1-chloro-2-nitrobenzenes, however, showed a similar dependence on the electronic properties of the para substituents, indicating that these substrates are conjugated to GSH via a similar transition state. Multiple regression analyses revealed that, besides electronic interactions, also steric and lipophilic restrictions appeared to play an important role in the GST 4-4-catalyzed GSH conjugation of 4-substituted 1-chloro-2-nitrobenzenes. Finally, the 4-substituted 1-chloro-2-nitrobenzenes were also used to extend the previously described substrate model for GST 4-4 [De Groot et al. (1995) Chem. Res. Toxicol. 8, 649-658], by which a specific steric restriction of substrates for GST 4-4 became clear.

SAR for a wide variety of heterocyclic replacements for a benzimidazole led to the discovery of functionalized 2-pyridyl amides as novel inhibitors of the hedgehog pathway. The 2-pyridyl amides were optimized for potency, PK, and drug-like properties by modifications to the amide portion of the mol. resulting in I (GDC-0449). Amide I produced complete tumor regression at doses as low as 12.5 mg/kg BID in a medulloblastoma allograft mouse model that is wholly dependent on the Hh pathway for growth and is currently in human clin. trials, where it is initially being evaluated for the treatment of BCC.

An improved process for the preparation of aromatic and heteroaromatic diorganozinc reagents and their subsequent reaction with electrophiles is presented. The new method, featuring the use of a 2,2,6,6-tetramethylpiperidyl (TMP) magnesium base in the presence of zinc chloride, is superior to the previous methods, which require the preparation of zinc bases. Specifically, the shorter reaction times under mild conditions provide an easier and more practical process, while the use of only a slight excess of the amide allows the isolation of products in high yields. These improvements are particularly significant for the large-scale preparation of organozincs and their subsequent reactions. Remarkably, beside the high kinetic activity, a wide range of functional groups is tolerated and sensitive heteroaromatics can easily be converted into the corresponding organometallic reagents and reacted with various electrophiles.

The synthesis of the platinum(II) μ2-sulfide complex [Pt2(μ2-S)2(PTA)4] (PTA = phosphatriazaadamantane), as a water-soluble analog of the known triphenylphosphine complex [Pt2(μ2-S)2(PPh3)4], was explored through a range of synthetic routes. A direct synthesis, from cis-[PtCl2(PTA)2] and Na2S·9H2O in benzene is the most effective, while attempted ligand substitution of the PPh3 ligands of [Pt2(μ2-S)2(PPh3)4] with PTA resulted in rearrangement of the {Pt2S2} core, and formation of a series of PTA-substituted trinuclear species of the general composition [Pt3(μ3-S)2(PPh3)x(PTA)6-x]2+. The fully-substituted complex [Pt3(μ3-S)2(PTA)6]2+ was also obtained when cis-[PtCl2(PTA)2] was reacted with a sulfide ion-exchange resin. Reaction of [PtCl2(cod)] (cod = 1,5-cyclooctadiene) with Na2S·9H2O in benzene gave a red solid identified as crude [Pt2(μ2-S)2(cod)2]. Reaction of this labile {Pt2S2} precursor with PTA gave [Pt2(μ2-S)2(PTA)4] along with PTA -oxide and -sulfide. ESI mass spectrometry was widely employed as a convenient tool for exploring this chem., in conjunction with 31P{1H} NMR spectroscopy. These PTA-Pt-sulfide species, especially those containing {Pt2S2} cores, have a tendency to decompose in solution Addnl. confirmation of the formation of [Pt2(μ2-S)2(PTA)4] was provided by its reaction with [Rh2(μ2-Cl)2(cod)2], giving the adduct [Pt2(μ3-S)2(PTA)4Rh(cod)]+, identified using ESI MS.
