Macrocyclic lactones, ketones, and ethers can be obtained in the High-Concentration Ring-Closing Metathesis (HC-RCM) reaction high yield selectivity at concentrations 40 to 380 times higher than those typically used by organic chemists for similar macrocyclizations. The new method consists of using tailored ruthenium catalysts together with applying vacuum distill off macrocyclic product as it is formed metathetical backbiting oligomers. Unlike classical RCM, no large quantities solvents are...
Simultaneous measurements of the lightning return-stroke current derivative at Canadian National (CN) Tower and corresponding electromagnetic pulse (LEMP) 2 km north tower have been performed since 1991 using broadband, high-resolution measurement systems. The recent installation global positioning systems for time synchronization CN stations has enabled correlation wavefront characteristics (peak, maximum derivative, 10-90% rise time) with those its LEMP. tower's electric magnetic fields...
Recent advances in the synthesis of macrocycles with musk scent via catalytic olefin metathesis are presented a particular emphasis on advantages offered by technology. The review includes short historical background about musks and to introduce subject. Substantial is given ring-closing (RCM) as tool for cyclic compounds such civetone, muscone, exaltolide, ambrettolide/isoambrettolide, yuzu lactone. bibliography 106 references.
High yielded and selective synthesis of macrocyclic unsaturated musk compounds from unbiased dienes using reactive distillation at high concentration.
Three new quinone‐containing Hoveyda‐type complexes have been synthesised and fully characterised. Their ability to suppress undesired double‐bond migration along the carbon chain during metathesis reactions was examined. It proved that these catalysts decrease amounts of side‐products with a shifted double bond in reaction mixture.
Synthesis of five Electron Withdrawing Group (EWG) activated Hoveyda-Grubbs' catalysts containing thioperfluoroalkyl, sulfone and ketone functions is reported. The catalytic activity these was well correlated with the σp values Hammett constants for respective EWGs. Importantly, one new gave good results in synthesis a macrocyclic precursor anti-HCV agent BILN2061.
One of the most important parameters in a lightning flash that is interest to researchers return-stroke current as it causes destructions and disturbances electrical telecommunication networks. In cases, can not be directly measured characteristics are determined from electric magnetic fields through use models. The main objective this work development model for an elevated object. Also, correlation wavefront (peak, maximum rate rise risetime) with its associated electromagnetic pulse...
A set of ruthenium complexes bearing a CAAC or uNHC ligand and dithiocatechol fragment have been obtained characterized spectroscopically. The activity Z-selectivity the newly catalysts were studied in selected model CM, self-CM, RCM olefin metathesis reactions. Intriguingly, contrast to structurally related NHC-bearing Ru4a Ru4b, analogues showed no only very little metathesis. Interestingly, despite being not productive reactions conducted solution, Ru8 enabled synthesis 16-membered...

Abstract Despite extensive research over the past three decades, there are still uncertainties regarding catalytic mechanism of human chitotriosidase-1. To fill gap, we reanalysed structural information available for this enzyme. Based on existing and new experimental data, complemented by multi-scale simulations, modelled full-length structure chitotriosidase-1 proposed general model its mechanism. We have elucidated role four highly conserved motifs present in glycoside hydrolases 18...
An optimized synthesis of a key intermediate Ru4 in substantially improved yield 50% and scale up to 1 gram was described.Such obtained quantitatively converted into useful quaternary ammonium tagged catalyst Ru1 (FixCat) immobilized metal-organic framework (MOF).Next, two challenging applications, not studied previously with hybrid Ru1@MOF were attempted.In the case RCM reaction yielding macrocyclic musk lactone, heterogeneous exhibited under high-dilution conditions high resistance towards...
