Enhancement of cyclic ether formation from polyalcohol compounds in high temperature liquid water by high pressure carbon dioxide

Cyclic ethers were produced by a dehydration reaction of polyalcohol compounds in high temperature liquid water, which was accelerated by the presence of carbon dioxide dissolved in the water. 3-hydroxytetrahydrofuran was produced by the dehydration of 1,2,4-butanetriol. Both tetrahydrofurfuryl alcohol and 3-hydroxytetrahydropyran were produced by the dehydration of 1,2,5-pentanetriol. Five-membered cyclic ethers were formed faster than six-membered cyclic ethers and the formation rates of the cyclic ethers depended strongly on the structure of the polyalcohol compounds. The position of the hydroxyl groups is crucial for the efficient intramolecular dehydration.

The dissociation of a wide range of oxygen-containing molecules following impact with electrons of carefully controlled energy is critically reviewed. Molecules considered range from diatomics, like O2 and CO, to large molecules of biological and technological interest. Dissociation mechanisms are discussed and, where possible, quantitative data for the various possible processes, ionization, attachment, dissociation, excitation, emission etc., are presented. Gaps and discrepancies in our current data base are highlighted. Both graphical and tabular data are presented.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Photo-oxidation of two malonamides, extractant models for minor actinides in nuclear fuel reprocessing

The photo-oxidation of two potential extractants, the N,N?-dimethyl, N, N?-dibutyl, tetradecyl malonamide (DMDBTDMA and the N, N ?-dimethyl, N, N?-dibutyl, dodecylethoxy malonamide (DMDBDDEMA) for minor actinides in nuclear fuel reprocessing was followed. The main photoproducts, identified by coupled techniques (GC/FTIR and GC/MS) are malonamides, monoamides and carbonylate derivatives. An irradiation, for 1 h, with a low mercury pressure lamp can destroy initial diamides diluted at 0.075 moll-1 in n-dodecane. With pure solutions of diamides (2.05 moll-1), destruction needs several hours to be complete. Both diamides only differ by an ether bond, their reactivity under different conditions of photo-oxidation is discussed.

Discovery of 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-benzonitriles and 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-pyridine-2?-carbonitriles as potent checkpoint kinase 1 (Chk1) inhibitors

An extensive structure-activity relationship study of the 3-position of a series of tricyclic pyrazole-based Chk1 inhibitors is described. As a result, 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-benzonitriles (4) and 4?-(1,4-dihydro-indeno[1,2-c]pyrazol-3-yl)-pyridine-2?-carbonitriles (29) emerged as new lead series. Compared with the original lead compound 2, these new leads fully retain the biological activity in both enzymatic inhibition and cell-based assays. More importantly, the new leads 4 and 29 exhibit favorable physicochemical properties such as lower molecular weight, lower Clog P, and the absence of a hydroxyl group. Furthermore, structure-activity relationship studies were performed at the 6- and 7-positions of 4, which led to the identification of ideal Chk1 inhibitors 49, 50, 51, and 55. These compounds not only potently inhibit Chk1 in an enzymatic assay but also significantly potentiate the cytotoxicity of DNA-damaging agents in cell-based assays while they show little single agent activity. A cell cycle analysis by FACS confirmed that these Chk1 inhibitors efficiently abrogate the G2/M and S checkpoints induced by DNA-damaging agent. The current work paved the way to the identification of several potent Chk1 inhibitors with good pharmacokinetics that are suitable for in vivo study with oral dosing.

Electron-induced damage of DNA and its components: Experiments and theoretical models

It is now over ten years since the seminal experiments of Leon Sanche’s group in Sherbrooke have compellingly shown that subexcitation electrons interacting with DNA could cause the occurrence of specific resonant processes which in turn would eventually lead to either single or double strand breaks in DNA materials, to the damaging of its molecular components and possibly to biological apoptosis. Since then a great deal of activity has been spurred by that initial work, with experiments and computations being carried out in several laboratories around the world. Hence, several components of the DNA molecular structure and make-up, i.e. from the purinic and pyrimidinic bases to the sugar and phosphate fragments, have been analysed in detail in the gas phase, on thin-film deposits on noble metals, and in some form of condensed phase, in interaction with low energy electrons. Likewise, several theoretical and computational approaches have been directed at the study of the molecular processes deemed to be crucially involved in the various steps of the energy deposition by the impinging electron onto the molecular networks. The aim of the present review is therefore to put together, after these ten years of intense activity, the major findings which have been consolidated from the broad variety of existing experiments and, at the same time, the main computational approaches which describe the extent of molecular damage following the initial electron attachment process. The present field, in fact, is becoming mature enough to profitably stand an overall evaluation of its experimental and theoretical/computational results and to further construct, from such a review, a starting point for the assessment of its future directions. After a detailed analysis of the experimental data, in the gas phase and in other phases, we shall therefore report the main computational tools and theoretical concepts employed today for the interpretation of the measurements at the molecular level. An overall analysis of the subject will be attempted in the last Section of this review.

Alcohols as alkylating agents in heteroarene C-H functionalization

Redox processes and radical intermediates are found in many biochemical processes, including deoxyribonucleotide synthesis and oxidative DNA damage. One of the core principles underlying DNA biosynthesis is the radical-mediated elimination of H2O to deoxygenate ribonucleotides, an example of ‘spin-centre shift’, during which an alcohol C-O bond is cleaved, resulting in a carbon-centred radical intermediate. Although spin-centre shift is a well-understood biochemical process, it is underused by the synthetic organic chemistry community. We wondered whether it would be possible to take advantage of this naturally occurring process to accomplish mild, non-traditional alkylation reactions using alcohols as radical precursors. Because conventional radical-based alkylation methods require the use of stoichiometric oxidants, increased temperatures or peroxides, a mild protocol using simple and abundant alkylating agents would have considerable use in the synthesis of diversely functionalized pharmacophores. Here we describe the development of a dual catalytic alkylation of heteroarenes, using alcohols as mild alkylating reagents. This method represents the first, to our knowledge, broadly applicable use of unactivated alcohols as latent alkylating reagents, achieved via the successful merger of photoredox and hydrogen atom transfer catalysis. The value of this multi-catalytic protocol has been demonstrated through the late-stage functionalization of the medicinal agents, fasudil and milrinone.
