A series of fluoroalkylated cyclic λ3-iodanes and their hydrochloride salts was prepared and used in a combination with sodium ascorbate in buffer or aqueous methanol mixtures for radical fluoroalkylation of a range of substituted indoles, pyrroles, tryptophan or its derivatives, and Trp residues in peptides. As demonstrated on several peptides, the aromatic amino acid residues of Trp, Tyr, Phe, and His are targeted with high selectivity to Trp. The functionalization method is biocompatible, mild, rapid, and transition-metal-free. The proteins myoglobin, ubiquitin, and human carbonic anhydrase I were also successfully functionalized.

Wang, Lei; Byun, Jeehye; Li, Run; Huang, Wei; Zhang, Kai A. I. published the artcile< Molecular Design of Donor-Acceptor-Type Organic Photocatalysts for Metal-free Aromatic C-C Bond Formations under Visible Light>, Application of C7H3FIN, the main research area is mol Donor Acceptor organic photocatalysts metal free aromatic carbon.

Metal-free and photocatalytic radical-mediated aromatic C-C bond formations offer a promising alternative pathway to the conventional transition metal-catalyzed cross-coupling reactions. However, the formation of aryl radicals from common precursors such as aryl halides is highly challenging due to their extremely high reductive potential. Here, we report a structural design strategy of donor-acceptor-type organic photocatalysts for visible light-driven C-C bond formations through the reductive dehalogenation of aryl halides. The reduction potential of the photocatalysts could be systematically aligned to be -2.04 V vs. SCE via a simple heteroatom engineering of the donor-acceptor moieties. The high reductive potential of the mol. photocatalyst could reduce various aryl halides into aryl radicals to form the C-C bond with heteroarenes. The design ability of the mol. photocatalyst further allowed the synthesis of a high LUMO (LUMO) polymer photocatalyst by a self-initiated free radical polymerization without compromising its LUMO level.

D’Agostini, Agnese; D’Auria, Maurizio published the artcile< Photochemical coupling between halogenoheterocyclic and heterocyclic derivatives>, COA of Formula: C6H5IO2S, the main research area is photochem coupling aryl aryl haloheterocycle heterocycle; iodothiophene iodofuran photochem coupling acetoxyallylthiophene acetoxyallylfuran.

The photochem. reaction between 5-iodo-heteroaryl derivatives I (X = O, R = H; X = S, R = Me, H, OMe) and both 3-heteroaryl allylic alcs. II (Y = O, S, R1 = H) and acetates II (Y = O, S, R1 = Ac) have been investigated. The presence of an alc. function was not compatible with photochem. coupling since compounds I were photoreduced in the presence of an alc. In contrast, the acetates gave the expected coupling products III (same X, Y, R, mixture of E and Z isomers). The presence of a weak electron-withdrawing group on the alkene induced an inverted regiochem. giving only aryl-aryl coupling products. The same behavior was observed using 2-(3-acetoxyprop-1-ynyl)thiophene, in which case only the product derived from aryl-aryl coupling was again observed When 2-prop-1-ynylthiophene was used as starting material, the product resulting from attack on the Me group was also observed Photochem. coupling between 2-thienylacetonitrile and halothienyl derivatives I (X = S, R = Me, H) gave no reaction product. In contrast, the irradiation of Me 2-thienylacetate and Me 2-(2-thienyl)propionate in the presence of I (X = S, R = Me, H) did give the corresponding aryl-aryl coupling products.

The 1H NMR and the IR CO group stretching frequencies of Me (3-, 4-, and 5-substituted 2-thiophenecarboxylate)s are observed Good linear correlations between the chem. shifts of the ring protons in Me (4- and 5-substituted 2-thiophenecarboxylate)s and those of the corresponding protons in substituted thiophenes were observed The coupling constants in Me (substituted 2-thiophenecarboxylate)s gave good correlations against the corresponding ones in substituted thiophenes. The IR carbonyl stretching frequencies in Me (5-substituted 2-thiophenecarboxylate)s were correlated reasonably well with the chem. shifts of 5-protons in 2-substituted thiophenes. The coupling constants in Me 2-thiophenecarboxylate series varied linearly with the electronegativities of the substituents.

Reversing the polarity in mols. is a versatile tool for expanding the boundaries of structural space. Despite a manifold of different umpolung methods available today, overcoming the inherent reactivity still remains a constant challenge in organic chem. The oxidative α-functionalization of ketones by external nucleophiles constitute such an example. Herein, we present a hypervalent F-iodane mediated umpolung of pyridyl ketones triggered by Lewis base/Lewis acid noncovalent interactions. A wide variety of external nucleophiles are introduced with high regioselectivity applying this substrate-directing concept.

A metal-free difunctionalization of alkynes to access tetrasubstituted olefins through spontaneous selenosulfonylation of vinylidene ortho-quinone methide (VQM) was described herein. The reaction was conducted under mild conditions without any catalysts or additives. Preliminary mechanism studies revealed that the formation of VQM was the key for this alkyne di-functionalization reaction. The reaction could be applied in the enantioselective asym. synthesis of axially chiral styrene. Furthermore, the selenosulfonylation adducts can be transformed into useful naphtho[2,1-b]furan and benzofuran scaffolds.

Clark, Jennifer M.; Salgado-Polo, Fernando; Macdonald, Simon J. F.; Barrett, Tim N.; Perrakis, Anastassis; Jamieson, Craig published the artcile< Structure-Based Design of a Novel Class of Autotaxin Inhibitors Based on Endogenous Allosteric Modulators>, Electric Literature of 167479-01-8, the main research area is structure based design steroid autotaxin inhibitors endogenous allosteric modulator.

Autotaxin (ATX) facilitates the hydrolysis of lysophosphatidylcholine to lysophosphatidic acid (LPA), a bioactive phospholipid, which facilitates a diverse range of cellular effects in multiple tissue types. Abnormal LPA expression can lead to the progression of diseases such as cancer and fibrosis. Previously, we identified a potent ATX steroid-derived hybrid (partially orthosteric and allosteric) inhibitor which did not form interactions with the catalytic site. Herein, we describe the design, synthesis, and biol. evaluation of a focused library of novel steroid-derived analogs targeting the bimetallic catalytic site, representing an entirely unique class of ATX inhibitors of type V designation, which demonstrate significant pathway-relevant biochem. and phenotypic biol. effects. The current compounds modulated LPA-mediated ATX allostery and achieved indirect blockage of LPA1 internalization, in line with the observed reduction in downstream signaling cascades and chemotaxis induction. These novel type V ATX inhibitors represent a promising tool to inactivate the ATX-LPA signaling axis.
