An efficient strategy for the synthesis of all carbon quaternary centres has been developed via Bronsted acid-promoted highly regioselective intermolecular Friedel-Crafts reactions of heteroarenes or arenes with spiro-epoxyoxindoles. In addition, we have successfully performed the ring opening reaction in relatively cheap condition using water as a solvent. Beneficially, we have utilized the methodology as the key step for the synthesis of advanced precursors of various natural and unnatural indole alkaloids.

We describe the preparation of two monomers that bear complementary nucleobases at the edges (guanine-2′-deoxycytidine and 2-aminoadenine-2′-deoxyuridine) and that are conveniently protected and activated for solid-phase automated DNA synthesis. We report the optimized synthetic routes leading to the four nucleobase derivatives involved, their cross-coupling reactions into dinucleobase-containing monomers, and their oligomerization in the DNA synthesizer.

The extensively developed ene-type enantioselective cycloisomerization of classical 1,n-enynes provides an efficient approach to chiral cyclic 1,4-dienes. In contrast, the catalytic asymmetric heteroarenyne (heteroarene-alkyne) cycloisomerization involving the dearomative transformation of endocyclic aromatic C=C bonds remains unknown. Herein, we communicate a PdH-catalyzed enantioselective heteroarenyne cycloisomerization reaction of alkyne-tethered indole substrates (formal 1,5- and 1,6-enynes). Based on this strategy, a variety of structurally diverse chiral spiro and fused indoline derivatives bearing quaternary stereocenters and exocyclic C=C bonds are afforded in moderate to excellent yields and excellent enantioselectivities (up to 98 % ee). The classical ene-type enantioselective 1,5-enyne cycloisomerization of N-vinylpropiolamides is also developed to afford chiral 2-pyrrolones in good to excellent ee values.

Novel benzo[d] thiazole-based analogues were synthesized with the aim of screening their in vitro anticancer activity. All the new derivatives 4-21 were evaluated against human hepatocellular carcinoma (HepG-2) and breast cancer cells (MCF-7) using doxorubicin as a reference drug. All compounds exhibited excellent potency against MCF-7 (IC50 values ranging from 0.71 +/- 0.4 to 1.04 +/- 0.7 mu M) and variable promising potency against HepG-2 (IC50 ranged from 2.53 +/- 2.5 to 3.47 +/- 3.4 mu M) comparing with the standard (IC50 = 1.03 +/- 0.8 mu M and 2.85 +/- 1.9 mu M, respectively) in addition to their safety towards the normal cell line. Compounds 5, 6, 7, 13 and 16 having the highest cytotoxic activity, were further evaluated for their EGFR inhibitory activity using Erlotinib as a reference drug. Molecular docking studies were performed for the promising compounds 5, 6 and 7 to interpret their detected enzymatic activities based upon their binding interactions with the receptor. Moreover, cell cycle analysis and detection of apoptosis induction illustrated that compounds 5 and 6 exhibited a significant pre G(1) and G(2)/M cell cycle arrest, in comparison with the untreated MCF-7 cells. In addition, compounds 5 and 6 elevated the levels of the oncogenic parameters; Bax, p53 and caspase-3 with decreased level of Bcl-2. These previous encouraging results of biological evaluation of the newly synthesized benzothiazoles could recommend an excellent framework toward the detection of new potent antitumor leads.

Electron-rich arenes are oxidatively photochlorinated in the presence of catalytic amounts of bromide ions, visible light, and 4CzIPN as organic photoredox catalyst. The substrates are brominated in situ in a first photoredox-catalyzed oxidation step, followed by a photocatalyzed ipso-chlorination, yielding the target compounds in high ortho/para regioselectivity. Dioxygen serves as a green and convenient terminal oxidant. The use of aqueous hydrochloric acid as the chloride source reduces the amount of saline by-products.

I found the field of Chemistry very interesting. Saw the article Ring Closing Metathesis Approach for the Synthesis of o-Terphenyl Derivatives published in 2019.0.

A linear synthesis of o-terphenyl derivatives has been delineated using ring closing metathesis (RCM) as the key step. In this approach, benzil derivatives upon allyl Grignard addition provides diphenyl-1,2-diallyl dihydroxy derivatives which undergo ring closing metathesis to afford tetrahydro terphenyl derivatives. Aromatization-driven dehydration then leads to a diverse set of electron rich and electron deficient o-terphenyls. Furthermore, oxidative coupling of electron rich o-terphenyls provides the corresponding triphenylene derivatives.

The front cover picture, provided by Burkhard Konig et al., illustrates how iodine solutions block most of the incoming light with the exception of a small part at the edge of the visible light spectral region. This spectral window (385-415 nm) with low absorptivity allows irradiation of an inexpensive anthraquinone photocatalyst, which can promote the iodination of electron-rich arenes and heteroarenes with high regioselectivity and good to excellent yields. Details are reported in the full paper on pages XXXX-XXXX (R. Narobe, S. J. S. Dusel, J. Iskra, B. Konig, Adv. Synth. Catal. 2019, 361, XXXX-XXXX;. DOI: 10.1002/adsc.201900298).

The molecular geometry observed for the compounds is predominantly distorted trigonal bipyramidal, the fact which was subsequently authenticated through X-ray analyses for (1-4). All the synthesized compounds have been bio-assayed for antileishmanial (Leishmania tropica KWH23) and Jack beans urease inhibitory activity, and human Lymphocytes were used to measure the general toxicity. Of these, (4) proved to be highly effective against the target species (Leishmania tropica KWH23), while being non-toxic towards the mammalian cells at levels below 0.74 mu gmL(-1), making it highly promising drug candidate. The high activities for (2, 4, and 6) against Jack beans Urease as compared to the reference standard demonstrate their significance in searching of therapeutic agents in future programs.

Selective tandem oxidative C-H olefination-azaMichael/aza-Wacker reaction of N-arylbenzamides is achieved by fine-tuning between base and additive to access valuable 3-oxoisoindolinyls and 3-oxoisoindolinylidenes, respectively. Careful optimization and control experiments provides a guiding principle in the design of a proposed catalytic cycle. The copper-iminium complex acting as a precursor for the binding of Ru catalyst was isolated and confirmed by X-ray diffraction. The versatility of this catalytic system has been demonstrated by the synthesis of biologically relevant molecules.
