The position of the N atom in the pentacyclic ring of heterocyclic molecules affects the excited-state decay: A case study of isothiazole and thiazole

The radiationless decay of the isothiazole and thiazole molecules in the gas phase is investigated by a combination of static MS-CASPT2 computations with dynamics simulations, and some deactivation pathways are identified leading from the lowest excited singlet (S1) state back to the electronic ground (S0) state. The dominant relaxation pathway of the excited isothiazole is found to involve out-of-plane ring deformation (ring puckering) at the C4=C5(H8)?S1 moiety, while the excited-state decay of thiazole can proceed through the ring puckering and S1?C2 bond cleavage pathways both of which happen at the S1?C2(H6) = N3 moiety. On the basis of the calculation results, we suggest that both ring-puckering and ring-opening routes should play rather important roles in the photophysics and photochemistry of heterocyclic molecules, and the position of the N atom in the heterocyclic ring has an effect on the excited state deactivation.

Spin-Spin Couplings Between 13C Nuclei in Five-Membered Heteroaromatic Ring Systems

A set of 1J(CC) spin-spin coupling constants are reported for 11 five-membered heteroaromatic molecules, including all relevant diazole, triazole, oxazole, oxadiazole, thiazole and thiadiazole systems.The coupling show a clear distinction between carbon-carbon bonds which are formally double or single, respectively.There seems to be no correlation of the couplings with the bond lengths concerned, in spite of some apparent trends.Potential applications of the couplings are discussed in assessing the aromaticity of five-membered heterocycles. – Keywords: 13C NMR Carbon-carbon coupling constants Heteroaromatic five-membered rings Diazoles Triazoles Oxazoles Oxadiazoles Thiazoles Thiadiazoles

Heterocyclic scaffolds for the treatment of Alzheimer?s disease

Background: The treatment and diagnosis of Alzheimer?s Disease (AD) are two of the most urgent goals for research around the world. The cognitive decline is generally associated with the elevated levels of extracellular senile plaques, intracellular neurofibrillary tangles (NFTs), and with a progressive shutdown of the cholinergic basal forebrain neurons transmission. Even if several key targets are under fervent investigation in the cure of AD, till now, the only approved therapeutic strategy is the treatment of symptoms by using cholinesterases inhibitors. It has been demonstrated that both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) enzymes are not only responsible of acetylcholine levels, but also play an pivotal role in A[1]-aggregation during the early stages of senile plaque formation. On the other hand the difficult management of AD is also related to effective diagnostic methods and efficient assays for the study of pathological features. In such complex a wide framework, heterocyclic molecules are essential backbone to build new and selective drugs as well as diagnostic probes. Methods: The goal of this review is to examine a selected sample of relevant applications of five- and six-membered heterocycles in AD’s therapeutic approaches. Results: Concerning the research on AD, the contribution of heterocyclic compounds is huge and here we report some representative examples. The review is organized in two main sections focused on five and six-membered heterocycles. The analyzed cases have been classified on the base of the structural features of molecules, taking into account the progressive increase in heteroatoms number. Conclusion: The discovery of an effective therapy or a diagnostic protocol for AD is still far, but consistent improvements are underway and contribution of heterocyclic compounds will be consistent and hopefully determinant.

Characterization of Matrix-Isolated Antiaromatic Three-Membered Heterocycles. Preparation of the Elusive Thiirene Molecule

The preparation and characterization of thiirene (4), a heterocyclic analogue of cyclobutadiene (1), which is derived from the photolysis of 1,2,3-thiadiazole (5), is described.The methodology exploits the C2v symmetry of the species 4 and utilizes isotopic labeling to aid in the characterization and narrow band-pass filters to protect thiirene from reaction with light of lambda > 2700 Angstroem, when it is generated photochemically.The evidence for 4 is based on (1) the fact that the same monolabeled species <13C>X is formed from distinctly labeled <13C>-1,2,3-thiadiazoles, (2) the photoisomerization of labeled X to ethynyl mercaptan and thioketene both with randomized label, and (3) the likelihood that the observed infrared bands attributed to 4 belong to a single species possessing cyclopropenoid character.In addition to thiirene, ethynyl mercaptan (14) and thioketene (15) are derived from 5.There are thus two paths (lambda > 2900 Angstroem) originating from 5 which give rise to 14 and 15.One stems from thiadiazole without the intervention of 4 and does not scramble hydrogens or carbons; the other is mediated by thiirene, which necessarily makes the C-H bonds equivalent.Irradiation (lambda ca. 3500 Angstroem) of doubly labeled <2H,13C> thiirene gives all four possible ethynyl mercaptans, indicating at least one exchange of hydrogens between carbon atoms must occur.The most reasonable explanation for this exchange presumes that both hydrogens reside on a single carbon atom at some point during the photoisomerization of thiirene to ethynyl mercaptan (14).

The effect of intermolecular forces on the glass transition of solute-polymer blends: 2. Extension to different solutes

The effects of intermolecular forces on the glass transition temperature (Tg) of various dye solutes in numerous polymer matrices have been investigated. The Tgs of these dye-polymer blends were found to depend on the polymer Tg, the dye Tg, their relative concentrations and the dye-polymer affinity. Attempts have been made to correlate increases in Tg with dye-polymer affinity using solubility parameters as a predictive tool. Poor correlations were obtained using global solubility parameters. Excellent correlations were made between elevation in Tg and enhanced dye-polymer affinity using averaged polar/hydrogen bonding solubility parameters. For all dye solutes, the Tg was low when there was a large mismatch in solubility parameters, increased as dye and polymer became more compatible and was at a maximum when the solubility parameters of both components were equal. The results also indicate that longer range polar and hydrogen bonding forces have a controlling influence on Tg.

Synthesis and application of stable nitroxide free radicals fused with carbocycles and heterocycles

Stable nitroxide free radicals have traditionally been associated with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) or its 4-substituted derivatives as relatively inexpensive and readily accessible compounds with limited possibilities for further chemical modification. Over the past two decades, there has been a resurgence of interest in stable free radicals with proper functionalization tuned for various applications. The objective of this review is to present recent results with synthetic methodologies to achieve stable nitroxide free radicals fused with aromatic carbocycles and heterocycles. There are two main approaches for accessing stable nitroxide free radicals fused with arenes, e.g., isoin-doline-like nitroxides: further functionalization and oxidation of phthalimide or inventive functionalization of pyrroline nitroxide key compounds. The latter also offers the con-structions of versatile heterocyclic scaffolds (furan, pyrrole, thiophene, 1,2-thiazole, selenophene, pyrazole, pyrimidine, pyridine, pyridazine, 1,5-benzothiazepine) that are fused with pyrroline or tetrahydropyridine nitroxide rings. The possible applications of these new stable nitroxide free radicals, such as covalent spin labels and noncovalent spin probes of proteins and nucleic acids, profluorescent probes, building blocks for construction of dual active drugs and electroactive materials, and substances for controlled free radical polymerization, are discussed.
