August, David P. published the artcileMaximizing Coordination Capsule-Guest Polar Interactions in Apolar Solvents Reveals Significant Binding, Formula: C10H12F6N4O6PdS2, the publication is Angewandte Chemie, International Edition (2016), 55(48), 15022-15026, database is CAplus and MEDLINE.

Guest encapsulation underpins the functional properties of self-assembled capsules yet identifying systems capable of strongly binding small organic mols. in solution remains a challenge. Most coordination capsules rely on the hydrophobic effect to ensure effective solution-phase association In contrast, we show that using non-interacting anions in apolar solvents can maximize favorable interactions between a cationic Pd₂L₄ host and charge-neutral guests resulting in a dramatic increase in binding strength. With quinone-type guests, association constants in excess of 10⁸ M^-1 were observed, comparable to the highest previously recorded constant for a metallosupramol. capsule. Modulation of optoelectronic properties of the guests was also observed, with encapsulation either changing or switching-on luminescence not present in the bulk phase.

Wentrup, Curt published the artcile3-pyridylnitrene, 2- and 4-pyrimidinylcarbenes, 3-quinolylnitrenes and 4-quinazolinylcarbenes. Interconversion, ring expansion to diazacycloheptatetraenes, ring opening to nitrile ylides and ring contraction to cyanopyrroles and cyanoindoles, Synthetic Route of 26187-28-0, the publication is Beilstein Journal of Organic Chemistry (2013), 743-753, database is CAplus and MEDLINE.

Precursors of 3-pyridylnitrene and 2- and 4-pyrimidinylcarbenes all afford mixtures of 2- and 3-cyanopyrroles on flash vacuum thermolysis, but 3-cyanopyrroles are the first-formed products. 3-Quinolylnitrenes and 4-quinazolinylcarbenes similarly afford 3-cyanoindoles. 2-Pyrimidinylcarbenes rearrange to 3-pyridylnitrenes, but 4-pyrimidinylcarbenes and 4-quinazolinylcarbenes do not necessarily rearrange to the corresponding 3-pyridylnitrenes or 3-quinolylnitrenes. The ring contraction reactions are interpreted in terms of ring opening of either the nitrenes or the diazacycloheptatetraenes to nitrile ylides.

Boursalian, Gregory B. published the artcilePd-Catalyzed Aryl C-H Imidation with Arene as the Limiting Reagent, Application In Synthesis of 68569-14-2, the publication is Journal of the American Chemical Society (2013), 135(36), 13278-13281, database is CAplus and MEDLINE.

An amine-N-oxide-ligated palladium complex, in conjunction with a silver cocatalyst, catalyzes imidation of arenes by the reagent N-fluorobenzenesulfonimide. The reaction enables imidation of a variety of arenes at or below room temperature, requires no coordinating directing group on the substrate, and gives synthetically useful yields with only 1 equiv of arene. Mechanistic data implicate an unusual mechanism devoid of commonly invoked organometallic intermediates: oxidation of the Pd catalyst occurs as the turnover-limiting step, while C-H bond functionalization occurs subsequently at a high oxidation state of the catalyst.

Nitroolefins are essential elements for both synthetic chem. and medicinal research. Despite significant improvements in nitration of olefin an efficient metal-free synthesis remains elusive so far. Herein, we disclose a new set of reagents to access nitroolefins in a single step under metal-free conditions. A wide range of olefins with diverse functionalities has been nitrated in synthetically useful yields. This transformation is operationally simple and exhibits excellent E-selectivity. Furthermore, site selective nitration in a complex setup makes this method advantageous.

Dianati, Vahid published the artcileImproving the Selectivity of PACE4 Inhibitors through Modifications of the P1 Residue, Application In Synthesis of 5153-73-1, the publication is Journal of Medicinal Chemistry (2018), 61(24), 11250-11260, database is CAplus and MEDLINE.

Paired basic amino acid cleaving enzyme 4 (PACE4), a serine endoprotease of the proprotein convertases family, has been recognized as a promising target for prostate cancer. We previously reported a selective and potent peptide-based inhibitor for PACE4, named the multi-Leu peptide (Ac-LLLLRVKR-NH₂ sequence), which was then modified into a more potent and stable compound named C23 with the following structure: Ac-DLeu-LLLRVK-Amba (Amba: 4-amidinobenzylamide). Despite improvements in both in vitro and in vivo profiles of C23, its selectivity for PACE4 over furin was significantly reduced. We examined other Arg-mimetics instead of Amba to regain the lost selectivity. Our results indicated that the replacement of Amba with 5-(aminomethyl)picolinimidamide increased affinity for PACE4 and restored selectivity. Our results also provide a better insight on how structural differences between S1 pockets of PACE4 and furin could be employed in the rational design of selective inhibitors.

Ieda, Naoya published the artcileDevelopment of photoredox-reaction-driven NO-releasing reagents and application for photomanipulation of vasodilation, Application In Synthesis of 26187-28-0, the publication is Yuki Gosei Kagaku Kyokaishi (2020), 78(11), 1048-1057, database is CAplus.

Nitric oxide (NO) is a signaling mol. that mediates vasodilation, neurotransmission, and immune response. Due to its instability in biol. environments, NO-releasing small-mol. compounds have been developed for biol. experiments and also as therapeutic reagents for vascular diseases. Although photocontrollable NO releasers are very useful chem. tools because of their precise operability in response to light irradiation, their biol. applications have been limited, mainly because they require UV light irradiation or contain metal ions with the potential to cause cytotoxicity. In order to overcome these problems, our group has developed visible-light-responsive NO releasers based on photoreodox reaction. These compounds are composed of two moieties, an NO-releasing moiety and a light-harvesting antenna moiety. After photoirradiation, photoinduced electron transfer from the NO releasing moiety to the antenna takes place, followed by NO release. Based on this system, we developed a blue-light-controllable NO releaser and a yellowish-green-light-controllable one, which are applicable for cellular and ex vivo experiments This account focuses on recent developments in photoredox-driven NO releasers and their applications for spatiotemporally controlled NO release in cells and ex vivo.

Kiyokawa, Kensuke published the artcileStraightforward Synthesis of 1,2-Dicyanoalkanes from Nitroalkenes and Silyl Cyanide Mediated by Tetrabutylammonium Fluoride, Computed Properties of 5153-73-1, the publication is Chemistry – A European Journal (2015), 21(3), 1280-1285, database is CAplus and MEDLINE.

A straightforward synthesis of 1,2-dicyanoalkanes RCH(CN)CH(R¹)CN [R = 4-OCH₃C₆H₄, thiophen-2-yl, pyridin-3-yl, etc.; R¹ = H; RR¹ = (CH₂)₄] by reacting nitroalkenes with trimethylsilyl cyanide in the presence of tetrabutylammonium fluoride was described. The reaction proceeds through a tandem double Michael addition under mild conditions. Employing the hypervalent silicate generated from trimethylsilyl cyanide and tetrabutylammonium fluoride was essential for achieving this transformation. Mechanistic studies suggest that a small amount of water included in the reaction media plays a key role. This protocol was applicable to various types of substrates including electron-rich and electron-deficient aromatic nitroalkenes and aliphatic nitroalkenes. Moreover, vinyl sulfones were found to be good alternatives, particularly for electron-deficient nitroalkenes. The broad substrate scope and functional group tolerance of the reaction makes this approach a practical method for the synthesis of valuable 1,2-dicyanoalkanes RCH(CN)CH(R¹)CN.

Kashanna, Jajula published the artcilePalladium catalyzed carboannulation of nitrostyrenes with internal alkynes: a new synthetic strategy for cross coupling/C-H annulation and facile access to indenones, Application In Synthesis of 5153-73-1, the publication is Tetrahedron Letters (2016), 57(14), 1576-1581, database is CAplus.

Palladium(II) catalyzed carboannulation reaction of internal alkynes with nitrostyrenes to afford 2,3-disubstituted indenones is reported. The annulation reaction proceeds through transmetalation of Pd(II) with aldehydes generated from the nitrostyrene (C-H activation) and insertion of the alkynes, followed by cyclization via intramol. nucleophilic addition of intermediate organopalladium(II) species. This reaction proceeded in moderate to good yields and with high regioselectivity. Electron-rich nitrostyrenes were transformed to the corresponding aldehydes in high yields without addition of any peroxide reagent.
