name: (S)-N,N-Dimethyl-1-ferrocenylethylamine, Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 31886-57-4, Name is (S)-N,N-Dimethyl-1-ferrocenylethylamine,introducing its new discovery.

A mixture of cis/trans isomers of phospha[1]ferrocenophanes equipped with one iPr group at the alpha position to the bridging PhP moiety was prepared. Both isomers (cis-4 and trans-4) were obtained as racemates and could be separated so that their thermal properties were investigated individually. The molecular structure of cis-4 was determined by single-crystal X-ray analysis showing a tilt angle alpha=26.35(8). Interconversion between both isomers occurred in the melt at elevated temperatures and revealed that the trans isomer is thermodynamically more stable. Structural and thermodynamic data was complemented by DFT calculations (B3PW91/6-311+G(d,p) and B3PW91-D3(BJ)/6-311+G(d,p)). Performance of thermal ring-opening polymerization (ROP) of trans-4 at 230 C gave polymers and cyclic oligomers. Gel permeation chromatography (GPC) of the sulfurized polymer resulted in a molecular weight of 62.5 kDa (Mw) and a polydispersity index of 1.39 (PDI). Mass spectrometric analysis of the oligomers showed the presence of cyclic species from dimers to heptamers. After sulfurization, preparative thin layer chromatography led to the separation of three isomeric dimers. Structural characterization of these dimers by single-crystal X-ray analysis led to the conclusion that the Fe?Cp bond breaks during the thermal ROP process. A mechanism similar to the known mechanism of the photolytic ROP of ferrocenophanes is proposed.

The catalytic C-H addition of pyridines to allenes has been achieved for the first time by using a half-sandwich scandium catalyst, thus constituting a straightforward and atom-economical route for the synthesis of alkenylated pyridine derivatives. The reaction proceeded regio- and stereoselectively, affording a new family of alkenylated pyridine compounds which are otherwise difficult to synthesize. A cationic Sc-eta2-pyridyl species was isolated and confirmed to be a key catalyst species in this transformation.

The effect of temperature, between 87 and 250 deg C, on the mobility of protonated amines in helium, air, CO2, and SF6 was studied by ion mobility spectrometry.In helium, the reduced mobility was found to decrease as the temperature was raised, due to an increase in the collision cross section, and was approximately proportional to T-1/2.In CO2, where clustering takes place at low temperatures, raising the temperature led to an increase in the reduced mobility, mainly due to breakdown of the clusters and a decrease in the effective mass of the ion.In air, where only little clustering was observed, the reduced mobility of light ions in creases with the temperature, while for heavy ions the oposite was found.In SF6, like in CO2, the increase of the reduced mobility with temperature was attributed to breakdown of clusters.An expression for the temperature dependence of the reduced mobility in each of these drift gases was determined semiempirically.

A quantum chemical study of the corrosion inhibition properties of pyridine and its derivatives at the aluminum electrode in hydrochloric acid was carried out. Based on the calculated results the compounds were adsorbed on the metal surface mainly in their protonated forms. The models of the inhibitors adsorption on the Al-surface were optimized with the MNDO method. It is found that the most favorable model is that the inhibitor molecule is adsorbed at the Al-surface in an inclined state, and the electron of the Al-surface is transferred to the inhibitor. The co-adsorption of the inhibitor and Cl- and H(ads) was discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.

Analytical chemists have increasingly turned their attention to drug discovery and drug analysis and to solve fundamental questions of biological significance in physiology and genetics. New technologies have been developed, and a variety of instruments have been redesigned for biomedical applications. The development of high-performance liquid chromatography (HPLC) opened a new era in biorelated fields and allowed faster separations of fragile macromolecules. Capillary column gas chromatography (GC)/mass spectrometry (MS) have been used to achieve more powerful separation and to perform structural analysis of molecules, and laboratory automation including robotics has become a powerful trend in both analysis and synthesis. Liquid chromatography (LC)/MS is more suitable for biomedical applications than GC/MS because almost all biomolecules are heat sensitive. Furthermore, a combination of various mass spectrometers has been used even for proteins directly. Improving the sensitivity of nuclear magnetic resonance spectrometry (NMR) has permitted a direct connection with LC. Purification of biomolecules on-line by LC has been performed since the development of chip-electrophoresis, On the other hand, computational chemical analysis is a promising technique given the advancing the hardware and software for use in chemical fields. In this review, a combination of chromatography and computational chemistry for use in drug discovery studies is described. Fast LC analysis using a column switching technique was introduced for aromatic amino acid metabolites and guanidino compounds. Recent developments in related technologies are also included from review papers.
