Intermolecular alkyl radical additions to enantiopure N-tert-butanesulfinyl aldimines

The sulfinyl group in (R)-N-tert-butanesulfinyl aldimines provides efficient control of the stereoselectivity in the intermolecular reactions with alkyl radicals. The methodology is applicable to aryl, heteroaryl, benzyl, and alkynyl imines, even those containing CN, CO2Me, COR, and OH groups. The best results are attained with hindered radicals (tertiary and secondary ones) without C=N bond reduction. This reaction complements the well-established organometallic additions to N-sulfinyl aldimines to obtain enantiomerically pure functionalized alpha-branched primary amines.

But sometimes, even after several years of basic chemistry education,, 2081-44-9 it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 2081-44-9!

Synthesis and activity of putative small-molecule inhibitors of the F-box protein SKP2

The tetrahydropyran 4-(((3-(2,2-dimethyltetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline was reported to disrupt the SCFSKP2 E3 ligase complex. Efficient syntheses of this tetrahydropyran derivative and analogues, including the des-dimethyl derivative 4-(((3-(tetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline, are described. The enantiomers of the des-dimethyl compound were obtained using Evans’ chiral auxiliaries. Structure-activity relationships for these tetrahydropyrans and analogues have been determined by measurement of growth-inhibitory activities in HeLa cells, which indicated a non-specific mechanism of action that correlates with inhibitor lipophilicity. However, preliminary data with (R)-and (S)-4-(((3-(tetrahydro-2H-pyran-4-yl)-4-phenylbutyl)amino)methyl)-N,N-dimethylaniline showed enantioselective inhibition of the degradation of p27 in a cell-based assay that acts as a reporter of SKP2 activity.

Ruthenium(II)-arene complexes with naphthalimide-tagged N,O- and N,N-chelating ligands: Synthesis and biological evaluation

A new family of ruthenium(II)-arene complexes with naphthalimide functionalized N,O- and N,N-chelating ligands of the general formula [Ru(eta6-p-cymene)Cl(L)] (2b-4b) (where: L = 4-[N-(2-((2-hydroxy-5-Br-phenyl)methyl imino)ethyl)]-N-butyl-1,8-naphthalimide (2a), 4-[N-(2-((2-hydroxy-5-Cl-phenyl)methyl imino)ethyl)]-N-butyl-1,8-naphthalimide (3a), and N-butyl-4-[N-(2-((2-hydroxy-5-NO2-phenyl)methylimino)ethyl)]-N-butyl-1,8-naphthalimide (4a), and [Ru(eta6-p-cymene) Cl(L?)]Cl (8b-9b) (where L? = N-(2,2?-dipyridylaminoethyl)-1,8-naphthalimide (8a) and N-(2,2?-dipyridylaminopropyl)-1,8-naphthalimide (9a) have been synthesized and characterized. The in vitro cytotoxic activities of the ligands (2a, 9a) and the complexes (2b-4b, and 8b-9b) have been evaluated against the human melanoma skin cancer (CRL7687) and normal noncancerous (CA-M75) cell lines. All the compounds exhibit potent cytotoxic activities with IC50 values of ?1 muM or less but displayed variable selectivity. The compounds with N,O-ligands were found to be less selective than those containing N,N-chelating ligands. Notably, complex 9b displayed the highest selectivity towards cancer cells over health cells. The interactions of the compounds with calf thymus DNA (CT-DNA) have also been investigated by UV-Vis and fluorescence spectra, ethidium bromide displacement assay and gel electrophoretic studies, which revealed that the compounds bind to CT-DNA moderately presumably through an intercalative mode.

Spectroelectrochemical properties of a Ru(ii) complex with a thiazolo[5,4-d]thiazole triarylamine ligand

A new bis-chelating ligand containing a triarylamine electron donor core fused with a thiazolo-thiazole electron acceptor, N,N?-(thiazolo[5,4-d]thiazole-2,5-diylbis(4,1-phenylene))bis(N-(pyridin-2-yl)pyridin-2-amine) (1) has been synthesised. This non-innocent ligand exhibits interesting electronic and spectral properties that can be tuned as a function of its redox state. In particular, modulation of the electronic state can be used to turn the fluorescence on and off. A dinuclear Ru(ii) terpyridine complex, [Ru2(tpy)2Cl2(1)](PF6)2 (2) was subsequently synthesised and the properties of each of the accessible redox states explored using in situ spectroelectrochemical techniques.

Utilization of aldoses as a carbonyl source in cyclocarbonylation of enynes

Figure presented. The reaction of enynes with acetyl-masked aldoses in the presence of a rhodium(I) catalyst resulted in cyclocarbonylation, thus avoiding the direct use of carbon monoxide, to afford bicyclic cyclopentenones. In rhodium catalysis, aldoses serve as a carbon monoxide equivalent by donating their carbonyl moieties on the acyclic aldehyde form to enynes. A variety of aldoses, including d-glucose, d-mannose, d-galactose, d-xylose, and d-ribose, can be used as a carbonyl source. Using the method, a wide variety of enynes were cyclocarbonylated in 22-67% yields. An asymmetric variant also proceeded with moderate to high enantioselectivity.

One-step synthesis of beta-C-glycosidic ketones in aqueous media: The case of 2-acetamido sugars

The one step synthesis of beta-D-C-glycosidic ketones by condensation of pentane-2,4-dione with unprotected N-acetyl-D-gluco-, manno-, and galactosamine in alkaline aqueous media has been explored. N-Acetyl-D-gluco- and mannosamine gave, in good yield, a mixture of the two gluco and manno C-glycosidic ketones, which were separated by crystallization after acetylation, whereas N-acetyl-D-galactosamine afforded the galacto C-glycosidic ketone which was isolated as its acetylated derivative in 50% yield.

Design, synthesis, biological evaluation of substituted benzofurans as DNA gyraseB inhibitors of Mycobacterium tuberculosis

DNA gyrase of Mycobacterium tuberculosis (MTB) is a type II topoisomerase and is a well-established and validated target for the development of novel therapeutics. By adapting the medium throughput screening approach, we present the discovery and optimization of ethyl 5-(piperazin-1-yl) benzofuran-2- carboxylate series of mycobacterial DNA gyraseB inhibitors, selected from Birla Institute of Technology and Science (BITS) database chemical library of about 3000 molecules. These compounds were tested for their biological activity; the compound 22 emerged as the most active potent lead with an IC50 of 3.2 ¡À 0.15 muM against Mycobacterium smegmatis DNA gyraseB enzyme and 0.81 ¡À 0.24 muM in MTB supercoiling activity. Subsequently, the binding of the most active compound to the DNA gyraseB enzyme and its thermal stability was further characterized using differential scanning fluorimetry method.
