Moiseeva, Ekaterina O.;Kosov, Anton D.;Borisova, Nataliya E.;Tarasevich, Boris N.;Dubinina, Tatiana V.;Tomilova, Larisa G. research published 《 Tetraiodophthalocyanines: Simple and convenient synthetic protocol and structural modification via Sonogashira cross-coupling reaction》, the research content is summarized as follows. Planar and sandwich-type iodo-substituted phthalocyanines – precursors for cross-coupling reactions were synthesized starting from 4-iodophthalonitrile via a novel user-friendly synthetic strategy. For this purpose, 4-iodophthalonitrile was prepared following the multi-step protocol, including nonclassical version of diazotization/iodination reaction in the presence of p-toluenesulfonic acid. Tetraiodophthalocyaninato Zn(II) was obtained using a solvent-free microwave-assisted synthesis. For the 1st time, the polyphosphoric acid was applied to the demetalation of halogen-substituted phthalocyanine complex. Under these conditions, demetalation of Zn(II) complex occurred in a good yield without the oxidation of peripheral iodo groups. The Sonogashira cross-coupling reaction between the 2(3),9(10),16(17),23(24)-tetraiodophthalocyanine and model (trimethylsilyl)acetylene resulted in a target compound in a high yield (94%). The versatility of iodo-substituted phthalocyanine precursors was demonstrated on the examples of the synthesis of novel tetra-(3-hydroxyprop-1-yn-1-yl)- phthalocyaninato Zn (II) (52% yield), bis[tetra(2-trimethylethynyl)phthalocyaninato] Lu (III) (45% yield). Target compounds were identified by NMR, IR spectroscopy, and mass spectrometry. UV-visible properties of target compounds were studied and compared with literature data. The key compounds were characterized by elemental anal.

Moinel, A.;Brochnow, M.;Aumaitre, C.;Giannoudis, E.;Fize, J.;Saint-Pierre, C.;Pecaut, J.;Maldivi, P.;Artero, V.;Demadrille, R.;Chavarot-Kerlidou, M. research published 《 Push-pull organic dyes and dye-catalyst assembly featuring a benzothiadiazole unit for photoelectrochemical hydrogen production》, the research content is summarized as follows. In this work, we report the design and the preparation of two new dyes and a mol. dyad for the photoelectrochem. hydrogen production from water in a dye-sensitized photoelectrochem. cell (DSPEC). We designed dyes that include a benzothiadiazole (BTD) and an indacenodithiophene (IDT) units, and we obtained a new mol. dyad by covalent coupling with the cobalt diimine-dioxime catalyst. The introduction of the benzothiadiazole core in the structure improves the absorption properties and leads to an extension of the spectrum in the visible range up to 650 nm. The photoelectrochem. properties of the new dyad were evaluated on pristine and lithium-doped NiO electrodes. We demonstrate that increasing the light harvesting efficiency of the dyad by introducing a IDT-BTD chromophore is clearly beneficial for the photoelectrochem. activity. We also demonstrate that lithium doping of NiO, which improves the electronic conductivity of the mesoporous film, leads to a significant increase in performance, in terms of TON and F. E., more than doubled with our new dyad. This BTD-based mol. system outperforms the results of previously reported dyads using the same catalyst.

Mohsenpour, Sajjad;Ameen, Ahmed W.;Leaper, Sebastian;Skuse, Clara;Almansour, Faiz;Budd, Peter M.;Gorgojo, Patricia research published 《 PIM-1 membranes containing POSS – graphene oxide for CO₂ separation》, the research content is summarized as follows. PIM-1 mixed matrix membranes (MMMs) were fabricated with polyhedral oligomeric silsesquioxane (POSS) and graphene oxide (GO) functionalized with POSS (GO-POSS), and tested for CO₂/N₂ (single gas) and CO₂/CH₄ (1:1, v:v gas mixture). The CO₂ permeability of the best performing fresh MMM (containing 0.05 wt% GO-POSS) was ∼ 12000 Barrer, which is 69% higher than that of the neat PIM-1 membrane, with about the same selectivity (CO₂/CH₄ selectivity ∼ 12 and CO₂/N₂ selectivity ∼ 20). In both cases, the gas separation data surpass the 2008 Robeson upper bound. In addition to the initial CO₂ permeability enhancement, the use of GO-POSS is an efficient strategy to slow down phys. aging. The MMM at a filler loading of 0.75 wt% showed less than half of the reduction in CO₂ permeability than the neat PIM-1 membrane 160 days after preparation (26% for the MMM vs 58% for the purely polymeric one).

Computational modeling was used to identify scaffolds with the potential to disrupt the interaction between HIV-1 integrase and lens epithelium-derived growth factor (HIV-1-IN-LEDGF/p75). Virtual screening of com. library collections led to the identification of N-(4-chlorophenyl)-7,7-dimethyl-2,5-dioxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxamide as a promising candidate. The synthesis of this compound and its derivatives involved the reaction of the corresponding carboxylic acid derivatives with aniline in the presence of coupling agent carbonyldiimidazole (CDI). This gave rise to N-2,5-dioxo-1,2,5,6,7,8-hexahydroquinoline-3-carboxamides in yields of 71-85%.

The construction of chiral tetrasubstituted carbon stereocenters is an ongoing challenge in synthetic organic chem. due to its prevalence in multiple disciplines. One efficient approach is the catalytic asym. C-C coupling reactions of a readily available racemic tertiary alkyl electrophile by simple organic nucleophiles.

Targeting cereblon (CRBN) is currently one of the most frequently reported proteolysis-targeting chimera (PROTAC) approaches, owing to favorable drug-like properties of CRBN ligands, immunomodulatory imide drugs (IMiDs). However, IMiDs are known to be inherently unstable, readily undergoing hydrolysis in body fluids. Here we show that IMiDs and IMiD-based PROTACs rapidly hydrolyze in commonly utilized cell media, which significantly affects their cell efficacy. We designed novel CRBN binders, Ph glutarimide (PG) analogs, and showed that they retained affinity for CRBN with high ligand efficiency (LE >0.48) and displayed improved chem. stability. Our efforts led to the discovery of PG PROTAC 4 c (SJ995973), a uniquely potent degrader of bromodomain and extra-terminal (BET) proteins that inhibited the viability of human acute myeloid leukemia MV4-11 cells at low picomolar concentrations (IC₅₀=3 pM; BRD4 DC₅₀=0.87 nM). These findings strongly support the utility of PG derivatives in the design of CRBN-directed PROTACs.

Materials capable of circularly polarized luminescence (CPL) have generated intensive interest for their potential applications. However, constructing chiral mols. with tunable CPL signals remains a challenge. In this paper, two pairs of binaphthylamine based chiral donors R/S-2 and R/S-3 were synthesized by Pd-catalyzed C-N coupling and intramol. oxidative coupling with good yields. Then three pairs of chiral D-A type mols. R/S-4∼6 can be synthesized by introducing two kinds of achiral acceptors. The extention of the chiral binaphthy skeleton endows these chiral compounds with CPL signals ranged from 417 nm to 544 nm in solutions and film states. The g_lum can be up to -2.9 × 10^-3 for R-2 in solution The introduction of terephthalonitrile as acceptor endow R/S-4 thermally activated delayed fluorescence (TADF). Furthermore, when benzophenone is chosen as achiral acceptor, the obtained chiral D-A mols. R/S-5 and R/S-6 can exhibit reversed CPL signals compared with their corresponding chiral donors. This work demonstrates the introduction of chiral D-A structure not only alters the wavelength of the CPL signals but also can reverse the CPL sign.
