Starting from Me salicylate and 2-amino-2-(hydroxymethyl)propane-1,3-diol, or 2-amino-2-methylpropane-1-ol, the 2-oxazoline derivatives of salicylic acid were synthesized. Reactions were performed by microwave irradiation in the presence of tetrabutylammonium bromide or metallic sodium as catalyst, as well as by conventional heating. Microwave-induced reaction of some diols, diamines and amino alcs. with Me salicylate gave mono- and/or bis- derivatives of salicylic acid. The mono- and bis-salicyloyl derivatives were transformed to the corresponding phenyl-azo derivatives The structure of one of the synthesized compound was proved by the X-ray anal. and the R-configuration on its stereocenter was confirmed. The antioxidant and cytotoxic activities of the synthesized derivatives were evaluated in a series of in vitro tests. Some of the compounds e,g., I, exhibited very strong activity against hydroxyl radical. Six tested compounds inhibited growth of MDA-MB-231 cells at a nanomolar concentration Two of the compounds e.g., II, showed high cytotoxicity against MCF7 cells, whereas four of the compounds showed high activity against K562 cells.

A practical strategy for the generation of virtually enantiomerically pure bis-cyclometalated iridium(III) complexes is reported. Accordingly, the reactions of [Ir(μ-Cl)(ppy)2]2 (ppy = cyclometalating 2-phenylpyridine) with (S)-4-tert-butyl-2-(2′-hydroxyphenyl)-2-oxazoline [(S)-1a], [Ir(μ-Cl)(pq)2]2 (pq = cyclometalating 2-phenylquinoline) with (S)-2-(2′-hydroxyphenyl)-4-isopropyl-2-oxazoline [(S)-1b], and [Ir(μ-Cl)(pbt)2]2 (pbt = cyclometalating 2-phenylbenzothiazole) with (S)-2-(2′-hydroxyphenyl)-4-isopropyl-2-thiazoline [(S)-1d] afforded diastereomeric mixtures of salicyloxazolinato or salicylthiazolinato complexes Λ/Δ-[Ir(ppy)2{(S)-1a-H}]PF6, Λ/Δ-[Ir(pq)2{(S)-1b-H}]PF6, and Λ/Δ-[Ir(pbt)2{(S)-1d-H}]PF6, resp., which could be resolved by silica gel flash chromatog.

Targeting protein-protein interactions (PPIs) offers tantalizing opportunities for therapeutic intervention for the treatment of human diseases. Modulating PPI interfaces with organic small mols. has been found to be exceptionally challenging, and few candidates have been successfully developed into clin. drugs. Meanwhile, the striking array of distinctive properties exhibited by metal compounds renders them attractive scaffolds for the development of bioactive leads. Here, we report the identification of iridium(III) compounds as inhibitors of the H-Ras/Raf-1 PPI. The lead iridium(III) compound 1 exhibited potent inhibitory activity against the H-Ras/Raf-1 interaction and its signaling pathway in vitro and in vivo, and also directly engaged both H-Ras and Raf-1-RBD in cell lysates. Moreover, 1 repressed tumor growth in a mouse renal xenograft tumor model. Intriguingly, the Δ-enantiomer of 1 showed superior potency in the biol. assays compared to Λ-1 or racemic 1. These compounds could potentially be used as starting scaffolds for the development of more potent Ras/Raf PPI inhibitors for the treatment of kidney cancer or other proliferative diseases.

The syntheses of oxidorhenium(V) complexes [ReOCl(L1a-c)2] (3a-c), equipped with the bidentate, mono-anionic phenol-dimethyloxazoline ligands HL1a-c are described. Ligands HL1b-c contain functional groups on the phenol ring, compared to parent ligand 2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-phenol H1a; namely a methoxy group ortho to the hydroxyl position (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-6-methoxyphenol, H1b), or a nitro group para to the hydroxyl position (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-4-nitrophenol, H1c). Furthermore, oxidorhenate(V) complexes (NBu4)[ReOCl3(L1a-b)] (2a-b) were synthesized for solid state structural comparisons to 3a-b. All novel complexes are fully characterized including NMR, IR and UV-Vis spectroscopy, MS spectrometry, X-ray crystallog., elemental anal. as well as cyclic voltammetry. The influence of functional groups (R = -H, -OMe and -NO2) on the catalytic activity of 3a-c was investigated in two benchmark catalytic reactions, namely cyclooctene epoxidation and perchlorate reduction In addition, the previously described oxidorhenium(V) complex [ReOCl(oz)2] (4), employing the phenol-oxazoline ligand 2-(4,5-dihydro-2-oxazolyl)phenol Hoz, was included in these catalysis studies. Complex 4 is a rare case in oxidorhenium(V) chem. where two stereoisomers could be separated and fully characterized. With respect to the position of the oxazoline nitrogen atoms on the rhenium atom, these two stereoisomers are referred to as N,N-cis and N,N-trans isomer. A potential correlation between spectroscopic and structural data to catalytic activity was evaluated.

The syntheses and characterizations of oxidorhenium(V) complexes trans-dichlorido [ReOCl2(PPh3)(L1a)] (trans-2a), cis-dichlorido [ReOCl2(PPh3)(L1b)] (cis-2b) and ethoxido-complex [ReO(OEt)(L1b)2] (4b), ligated with the dimethyloxazoline-phenol ligands HL1a and HL1b are described. The bidentate ligand HL1a (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)phenol) is unsubstituted on the phenol ring; ligand HL1b (2-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)-4-nitrophenol) contains a nitro group in para-position to the hydroxy group. In the reaction of precursor complex [ReOCl3(PPh3)2] and HL1a the two stereoisomers cis/trans-2a, with respect to chlorido ligands, are formed. The solid state structures of both isomers cis- and trans-2a were determined by single crystal x-ray diffraction anal. In contrast, with ligand HL1b, only the cis-isomer cis-2b was obtained. Ethoxido-complex 4b is exclusively obtained when precursor [ReOCl3(OPPh3)(SMe2)] is reacted with 2 equiv of HL1b in ethanol in the presence of the base 2,6-dimethylpyridine (lutidine). If no lutidine was added, chlorido-complex [ReOCl(L1b)2] (3b) was obtained. Complexes [ReOCl2(PPh3)(L1a)] (cis/trans-2a), [ReOCl2(PPh3)(L1b)] (cis-2b), [ReO(OMe)(L1a)2] (4a) and [ReO(OEt)(L1b)2] (4b) were tested as homogeneous catalysts in the benchmark reaction of cyclooctene epoxidation The influence of isomerism and effects of ligand substitutions on catalytic activity was studied. Based on the time-conversion plots cis/trans-isomerism does not influence catalytic activity, but electron-withdrawing substituents, as in cis-2b, 3b and 4b, show a beneficial effect.

Alternatives to Phosphinooxazoline (t-BuPHOX) Ligands in the Metal-Catalyzed Hydrogenation of Minimally Functionalized Olefins and Cyclic β-Enamides was written by Biosca, Maria; Magre, Marc; Coll, Merce; Pamies, Oscar; Dieguez, Montserrat.

A new series of readily accessible iridium- and rhodium-phosphite/oxazoline catalytic systems that can efficiently hydrogenate, for the first time, both minimally functionalized olefins and functionalized olefins, such as Et 3-phenylbut-2-enoate, Et (2Z)-3-cyclohexyl-3-phenylprop-2-enoate, [(1E)-1-methyl-1-propen-1-yl]benzene, etc. (62 examples in total), with high enantioselectivities (up to >99% ee) and conversions has been reported. The phosphite-oxazoline ligands, which are readily available in only two synthetic steps, are derived from previous privileged 4-alkyl-2-[2-(diphenylphosphino)phenyl]-2-oxazoline (PHOX) ligands by replacing the phosphine moiety by a biaryl phosphite group and/or the introduction of a methylene spacer between the oxazoline and the Ph ring. The modular design of the ligands has given the opportunity not only to overcome the limitations of the iridium-PHOX catalytic systems in the hydrogenation of minimally functionalized Z-olefins and 1,1-disubstituted olefins, but also to expand their use to unfunctionalized olefins containing other challenging scaffolds (e.g., exocyclic benzo-fused and triaryl-substituted olefins) and also to olefins with poorly coordinative groups (e.g., α,β-unsaturated lactams, lactones, alkenylboronic esters, etc.) with enantioselectivities typically >95% ee. Moreover, both enantiomers of the hydrogenation product could be obtained by simply changing the configuration of the biaryl phosphite moiety. Remarkably, the new catalytic systems also provided excellent enantioselectivities (up to 99% ee) in the asym. hydrogenation of another challenging class of olefins – the functionalized cyclic β-enamides, such as N-(6-bromo-3,4-dihydronaphthalen-2-yl)acetamide, N-(2H-chromen-3-yl)acetamide, N-(8-methoxy-3,4-dihydronaphthalen-2-yl)acetamide, etc. Again, both enantiomers of the reduced amides could be obtained by changing the metal from Ir to Rh. The environmentally friendly propylene carbonate which can be used with no loss of enantioselectivity was also demonstrated. Another advantage of the new ligands over the PHOX ligands is that the best ligands are derived from the affordable (S)-phenylglycinol rather than from the expensive (S)-tert-leucinol.
