Reversibly photoswitchable nucleosides: Synthesis and photochromic properties of diarylethene-functionalized 7-deazaadenosine derivatives

Photochromic nucleosides were designed that combine the structural features and molecular recognition properties of nucleic acids with the light-sensitivity of diarylethenes. Target compounds 1a-c consist of a 7-deazaadenosine unit that is linked to a thiophene as the second aryl functionality via a 1,2-cyclopentenyl linker. These nucleoside analogues undergo a reversible electrocyclic rearrangement, generating strongly colored closed-ring isomers upon irradiation with UV-light, while exposure to light in the visible range triggers the cycloreversion to the colorless opened-ring form. UV-vis spectroscopy, HPLC, and 1H NMR measurements revealed recognition of complementary thymidine and up to 97% conversion to the thermally stable closed-ring isomers after illumination with UV-light. The required wavelength for ring closure was found to vary depending on the substituents attached to the thiophene moiety. In a first design step, we used this important feature of diarylethenes to shift the switching wavelength from initially 300 nm (1a) to 405 nm (1cH+). In a second step, we generated a pair of orthogonal switches, differing enough in their respective switching wavelengths to be controlled independently in the same sample. Finally, a molecular switch was developed that showed both photochromism and acidichromism, thereby illustrating the possibility to gate the spectral properties to multiple stimuli. These new photochromic nucleosides represent useful building blocks for the generation of light-sensitive nucleic acids either by inducing conformational changes upon isomerization or by exploring the different spectral properties of the closed and opened isomers, for example, for use as reversible fluorescence quenchers.

Selective Heck reaction of electron-rich aryl bromides with cyclic alkenones

A simple and efficient protocol for the Heck reaction of cyclic alkenones with electron-rich aryl bromides has been developed. A ligand combination of X-Phos and tri-tert-butylphosphonium hydrogen tetrafluoroborate in the presence of Pd(PPh3)2Cl2 and Na2CO3 in DMSO was found to be efficient and selective for electron-rich aryl bromides with high substrate scope for cyclic alkenones.

Degradation of the petroleum component’s monomethylbenzothiophenes on exposure to light

The photochemical degradation of monomethylated benzo[b]thiophenes in aqueous solution was studied to elucidate the fate of crude oil components after an oil spill. One principal reaction pathway involves oxidation of the methyl group(s) to the carboxylic acids via aldehydes. Another pathway leads via oxidation of the thiophene ring to the quinone and then, after ring opening, to 2-sulfobenzoic acids as the ultimate products for all compounds. Opening of the benzo ring is also seen in which case thiophene aldehydes or ketones are formed.

Transition-Metal-Free Synthesis of C3-Arylated Benzofurans from Benzothiophenes and Phenols

We report a transition-metal-free synthesis of benzofurans from benzothiophenes and phenols that exploits the unique reactivity of sulfoxides. Through a sequence involving an interrupted Pummerer reaction and [3,3] sigmatropic rearrangement, phenols can be combined with readily accessible yet synthetically unexplored benzothiophene S-oxides to provide C3-arylated benzofuran products. The products from this approach can undergo subsequent functionalization to gain access to a range of important benzofuran derivatives.

Ir-catalyzed cascade c-h fusion of aldoxime ethers and heteroarenes: Scope and mechanisms

A concise synthesis of phenanthridine derivatives is achieved by an iridium-catalyzed direct fusion of oxime ethers and heteroarenes, which is a successful example of a cascade C-H/C-H cross-coupling/cyclization strategy for polycyclic heteroaromatic synthesis. By subtle tuning of the reaction conditions, both benzo- and simple five-membered heteroarenes are suitable substrates under similar but different conditions. The key is the right choice of a silver salt. The detailed mechanistic study discloses that the first C-H/C-H cross-coupling step involves an [IrII]-[IrIV] catalytic cycle, which needs Ag2O as the oxidant. For the second cyclization step, a radical process takes control in the reactions of benzoheteroarenes and Ag2O is required; however, a C-H cyclization functions in the reactions of simple five-membered heteroarenes involving an [IrI]-[IrIII] catalytic cycle, and AgTFA is necessary.

Structure-based design of potent and ligand-efficient inhibitors of CTX-M class A beta-lactamase

The emergence of CTX-M class A extended-spectrum beta-lactamases poses a serious health threat to the public. We have applied structure-based design to improve the potency of a novel noncovalent tetrazole-containing CTX-M inhibitor (Ki = 21 muM) more than 200-fold via structural modifications targeting two binding hot spots, a hydrophobic shelf formed by Pro167 and a polar site anchored by Asp240. Functional groups contacting each binding hot spot independently in initial designs were later combined to produce analogues with submicromolar potencies, including 6-trifluoromethyl-3H-benzoimidazole-4- carboxylic acid [3-(1H-tetrazol-5-yl)-phenyl]-amide, which had a Ki value of 89 nM and reduced the MIC of cefotaxime by 64-fold in CTX-M-9 expressing Escherichia coli. The in vitro potency gains were accompanied by improvements in ligand efficiency (from 0.30 to 0.39) and LipE (from 1.37 to 3.86). These new analogues represent the first nM-affinity noncovalent inhibitors of a class A beta-lactamase. Their complex crystal structures provide valuable information about ligand binding for future inhibitor design.
