Cyclic Ru-phenolates were synthesized, and these compounds were used as olefin metathesis catalysts. Investigation of their catalytic activity pointed out that, after activation with chemical agents, these catalysts promote ring-closing metathesis (RCM), enyne and cross-metathesis (CM) reactions, including butenolysis, with good results. Importantly, these latent catalysts are soluble in neat dicyclopentadiene (DCPD) and show good applicability in ring-opening metathesis polymeriyation (ROMP) of this monomer. Olefin metathesis catalysis: Investigation of the catalytic activity of Ru phenolate catalysts pointed out that, after activation with chemical agents, these catalysts promote ring-closing metathesis (RCM), enyne, and cross-metathesis (CM) reactions, including butenolysis, with good results (see scheme, Mes=2,4,6-trimethylphenyl, Cy=cyclohexyl). The phenolanate catalysts, well soluble in dicyclopentadiene (DCPD), also show good applicability in ring-opening metathesis polymerization (ROMP) of this monomer.

Starting from a purified cashew nut shell extract containing mostly anacardic acid derivatives, the tsetse fly attractants 3-ethyl- and 3-propylphenol were selectively synthesised. The mixture was first converted into 3-(non-8-enyl)phenol in 98% purity via ethenolysis and distillation with concomitant decarboxylation. The olefinic side chain was then shortened by isomerising cross-metathesis with short-chain olefins in the presence of a [Pd(mu-Br)(tBu3P)]2 isomerisation catalyst and a second-generation Hoveyda-Grubbs catalyst, and the synthesis was completed by a hydrogenation step.

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.Quality Control of: (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, you can also check out more blogs about301224-40-8

By natural product inspired diversity-oriented synthesis, we had developed a new class of selective antagonist, IKM-159, for the AMPA receptor. Here, we report syntheses of IKM-159 and skeletally diverse five analogues in racemic forms, two of which are heterotricycles and the other three compounds are truncated analogues, to study the structure-activity relationships. The key reactions are two domino reactions including Ugi/Diels-Alder reaction and domino metathesis reaction. An exceptionally high level of regiocontrol in the cross metathesis reaction is also reported. Georg Thieme Verlag Stuttgart New York.

Catalytic transformation of renewable feedstocks into fine chemicals is in high demands and olefin metathesis is a sophisticated tool for biomass conversion. Nevertheless, the large-scale viability of such processes depends on the conversion efficiency, energy efficiency, catalytic activity, selective conversion into desired products, and environmental footprint of the process. Therefore, conversions of renewables by using simple, swift, and efficient methods are desirable. A microwave-assisted ethenolysis and alkenolysis (using 1,5-hexadiene) of canola oil and methyl esters derived from canola oil (COME) and waste/recycled cooking oil (WOME) was carried out by using ruthenium-based catalytic systems. A systematic study using 1st and 2nd generation Grubbs and Hoveyda?Grubbs catalysts was carried out. Among all ruthenium catalysts, 2nd generation Hoveyda?Grubbs catalyst was found to be highly active in the range of 0.002?0.1 mol % loading. The conversions proved to be rapid providing unprecedented turnover frequencies (TOFs). High TOFs were achieved for ethenolysis of COME (21 450 min?1), direct ethenolysis of canola oil (19 110 min?1), for WOME (15 840 min?1) and for cross-metathesis of 1,5-hexadiene with COME (10 920 min?1). The ethenolysis of commercial methyl oleate was also performed with a TOF of 8000 min?1 under microwave conditions.

Amino acid based polymers are of interest for a variety of biomaterial applications including drug delivery, proteomics, and tissue engineering. A new class of polymers bearing amino acids and dipeptides has been prepared using acyclic diene metathesis (ADMET) to create copolymers of polyethylene with linear amino alcohol, branched amino acid, or branched peptide substituents termed bio-olefins. Monomers with the amino acid/dipeptide functionality attached through both the N and C-terminus have been prepared, and a discussion on the synthesis of the monomers and a comparison of the thermal properties of the resulting polymers are discussed. The resulting highly functionalized polymers are strong, film-forming materials with moduli in the range of LDPE with molecular weights typical of polycondensation polymers, i.e. Nylon and PET.

MandelalideA and three congeners had recently been isolated as the supposedly highly cytotoxic principles of an ascidian collected off the South African coastline. Since these compounds are hardly available from the natural source, a concise synthesis route was developed, targeting structure 1 as the purported representation of mandelalideA. The sequence involves an iridium-catalyzed two-directional Krische allylation and a cobalt-catalyzed carbonylative epoxide opening as entry points for the preparation of the major building blocks. The final stages feature the first implementation of terminal acetylene metathesis into natural product total synthesis, which is remarkable in that this class of substrates had been beyond the reach of alkyne metathesis for decades. Synthetic 1, however, proved not to be identical with the natural product. In an attempt to clarify this issue, NMR spectra were simulated for 20 conceivable diastereomers by using DFT followed by DP4 analysis; however, this did not provide a reliable assignment either. The puzzle was ultimately solved by the preparation of three diastereomers, of which compound 6 proved identical with mandelalideA in all analytical and spectroscopic regards. As the entire “northern sector” about the tetrahydrofuran ring in 6 shows the opposite configuration of what had originally been assigned, it is highly likely that the stereostructures of the sister compounds mandelalidesB-D must be corrected analogously; we propose that these natural products are accurately represented by structures 68-70. In an attempt to prove this reassignment, an entry into mandelalidesC and D was sought by subjecting an advanced intermediate of the synthesis of 6 to a largely unprecedented intramolecular Morita-Baylis-Hillman reaction, which furnished the gamma-lactone derivative 74 as a mixture of diastereomers. Whereas (24R)-74 was amenable to a hydroxyl-directed dihydroxylation by using OsO4/TMEDA as the reagent, the sister compound (24S)-74 did not follow a directed path but simply obeyed Kishi’s rule; only this unexpected escape precluded the preparation of mandelalidesC and D by this route. A combined spectroscopic and computational (DFT) study showed that the reasons for this strikingly different behavior of the two diastereomers of 74 are rooted in their conformational peculiarities. This aspect apart, our results show that the OsO4/TMEDA complex reacts preferentially with electron deficient double bonds even if other alkenes are present that are more electron rich and less encumbered. Finally, in a brief biological survey authentic mandelalideA (6) was found to exhibit appreciable cytotoxicity only against one out of three tested human cancer cell lines and all synthetic congeners were hardly active. No significant fungicidal properties were observed.

A de novo synthetic method towards apiose, a structurally unusual furanose, is reported. The key feature is sequential metal catalysis consisting of the palladium-catalyzed asymmetric intermolecular hydroalkoxylation of an alkoxyallene and subsequent ring-closing metathesis (RCM). This strategy enabled the efficient synthesis of various apiose-containing disaccharides and a unique convergent synthesis of trisaccharides.

Ryanodol (1) exists in nature in the form of the 1H-pyrrole-2-carboxylate ester derivative known as ryanodine, which is a potent modulator of the calcium release channel. The pentacyclic ABCDE-ring system of 1 is fabricated with eight oxy groups, three methyl groups, and one isopropyl group. All the eight tetrasubstituted stereocenters are concentrated within the 10-carbon ABDE framework. The total synthesis of this exceptionally complex molecule was achieved in 22 steps from the simple C2-symmetric tricycle 8. The synthetic route is based on installation of the seven stereogenic centers and formation of the four C-C bonds within the highly congested multicyclic format. The novel and flexible strategy developed here will enable the generation of chemical derivatives with different functional properties toward calcium release channels.
