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.

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.

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.

Continuous-flow synthesis of functionalized phenols by aerobic oxidation of grignard reagents

Phenols are important compounds in chemical industry. An economical and green approach to phenol preparation by the direct oxidation of aryl Grignard reagents using compressed air in continuous gas-liquid segmented flow systems is described. The process tolerates a broad range of functional groups, including oxidation-sensitive functionalities such as alkenes, amines, and thioethers. By integrating a benzyne-mediated in-line generation of arylmagnesium intermediates with the aerobic oxidation, a facile three-step, one-flow process, capable of preparing 2-functionalized phenols in a modular fashion, is established. Putting on airs: Aerobic oxidation of (hetero)aryl Grignard reagents using compressed air proceeds with a gas-liquid continuous-flow system, thus enabling preparation of fucntionalized phenols. By integrating an in-line generation of ArMgBr intermediates with the aerobic oxidation, ortho-functionalized phenols can be assembled. The method demonstrates good functional-group (FG) compatibility, mild reaction conditions, and short reaction times.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 130-03-0, you can also check out more blogs about130-03-0

Synthesis of novel 2-aminoimidazo[4,5-b]pyridines, including the thieno analogue of the cooked-food mutagen IFP

Eight new compounds, including three new ring systems obtained via the Friedlunder condensation of ortto-aminothiophenecarbaldehydes 11, 21 and 24 with creatinine (8), are reported. The condensation afforded 1, which is the thieno analogue of the cooked-food mutagen IFP (2-amino-1,6-dimethylfuro[2,3-e] imidazo[4,5-b]pyridine), and the benzothieno[2,3-e]- and benzothieno[3,2-e] imidazo[4,5-b]pyridines 2 and 3. Attempts to condense 11 with isocreatinine (12) were unsuccesful. Desulfurization of 3 gave the known cooked-food carcinogen PhIP, The 2-nitro (4) and 2-hydroxy (5) derivatives of 3 are reported. The related 2-amino-1-methyl-imidazo[4,5-b]benzothiophene (25) was synthesized by a different route. Fully assigned 1H and 13C nmr data of all new compounds are reported.

Enzymatic enantioselective decarboxylative protonation of heteroaryl malonates

The enzyme aryl/alkenyl malonate decarboxylase (AMDase) catalyses the enantioselective decarboxylative protonation (EDP) of a range of disubstituted malonic acids to give homochiral carboxylic acids that are valuable synthetic intermediates. AMDase exhibits a number of advantages over the non-enzymatic EDP methods developed to date including higher enantioselectivity and more environmentally benign reaction conditions. In this report, AMDase and engineered variants have been used to produce a range of enantioenriched heteroaromatic alpha-hydroxycarboxylic acids, including pharmaceutical precursors, from readily accessible alpha-hydroxymalonates. The enzymatic method described here represents an improvement upon existing synthetic chemistry methods that have been used to produce similar compounds. The relationship between the structural features of these new substrates and the kinetics associated with their enzymatic decarboxylation is explored, which offers further insight into the mechanism of AMDase. Versatile decarboxylase: Aryl malonate decarboxylase (AMDase) and engineered variants have been shown to catalyse the enatioselective decarboxylative protonation of a range of alpha-heteroaryl alpha-hydroxy malonates with excellent yields and enantioselectivity (see scheme).
