Synthesis and Evaluation of Sterically Demanding Ruthenium Dithiolate Catalysts for Stereoretentive Olefin Metathesis

Dithiolate ligands have recently been used in ruthenium-catalyzed olefin metathesis and have provided access to a kinetically E selective pathway through stereoretentive olefin metathesis. The typical dithiolate used is relatively simple with low steric demands imparted on the catalyst. We have developed a synthetic route that allows access to sterically demanding dithiolate ligands. The catalysts generated provided a pathway to study the intricate structure-activity relationships in olefin metathesis. It was found that DFT calculations can predict the ligand arrangement around the ruthenium center with remarkable accuracy. These dithiolate catalysts proved resistant to ligand isomerization and were stable even under forcing conditions. Additionally, catalyst initiation and olefin metathesis studies delivered a better understanding to the interplay between dithiolate ligand structure and catalyst activity and selectivity.

Chemoselective cross-metathesis reaction between electron-deficient 1,3-dienes and olefins

Chemoselective cross-metathesis reactions between methyl sorbate or 1,3-dienic amides and various olefins in the presence of the Grubbs-Hoveyda catalyst have been investigated. Cross-metathesis reactions turned out to be more chemoselective with 1,3-dienic amides than with 1,3-dienic esters.

Catalytic surfactants for ring-opening metathesis polymerization and ring-closing metathesis in non-degassed micellar solutions

Metathesis catalysts bearing long alkyl chains and analogous to Hoveyda’s catalyst have been synthesized. Their surface-active properties have been characterized by formation of Langmuir films at the air-water interface. They have been dispersed in micelles formed in non-degassed water and been used in polymerization of a hydrophilic monomer. These surfactants are therefore the first inisurf molecules for metathesis polymerization that are air-stable. Their ability to catalyze ring-closing metathesis in water has also been evaluated.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 301224-40-8 is helpful to your research., Reference of 301224-40-8

Z-selective olefin metathesis on peptides: Investigation of side-chain influence, preorganization, and guidelines in substrate selection

Olefin metathesis has emerged as a promising strategy for modulating the stability and activity of biologically relevant compounds; however, the ability to control olefin geometry in the product remains a challenge. Recent advances in the design of cyclometalated ruthenium catalysts has led to new strategies for achieving such control with high fidelity and Z selectivity, but the scope and limitations of these catalysts on substrates bearing multiple functionalities, including peptides, remained unexplored. Herein, we report an assessment of various factors that contribute to both productive and nonproductive Z-selective metathesis on peptides. The influence of sterics, side-chain identity, and preorganization through peptide secondary structure are explored by homodimerization, cross metathesis, and ring-closing metathesis. Our results indicate that the amino acid side chain and identity of the olefin profoundly influence the activity of cyclometalated ruthenium catalysts in Z-selective metathesis. The criteria set forth for achieving high conversion and Z selectivity are highlighted by cross metathesis and ring-closing metathesis on diverse peptide substrates. The principles outlined in this report are important not only for expanding the scope of Z-selective olefin metathesis to peptides but also for applying stereoselective olefin metathesis in general synthetic endeavors.

Chelated ruthenium catalysts for Z -selective olefin metathesis

We report the development of ruthenium-based metathesis catalysts with chelating N-heterocyclic carbene (NHC) ligands that catalyze highly Z-selective olefin metathesis. A very simple and convenient procedure for the synthesis of such catalysts has been developed. Intramolecular C-H bond activation of the NHC ligand, promoted by anion ligand substitution, forms the appropriate chelate for stereocontrolled olefin metathesis.

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.SDS of cas: 301224-40-8, you can also check out more blogs about301224-40-8

Unified strategy for the synthesis of the “miscellaneous” Lycopodium alkaloids: Total synthesis of (¡À)-lyconadin A

Total synthesis of the Lycopodium alkaloid lyconadin A was achieved in 18 steps starting from a readily available vinylogous ester and bromopicoline. The key step in the total synthesis is a proximity-driven oxidative C-N bond-forming reaction that yields the lyconadin pentacycle from a tetracyclic precursor. The key tetracycle, which has been prepared for the first time, is a versatile intermediate that may be utilized for the total synthesis of a variety of Lycopodium alkaloids. Critical to the success of this plan was the efficient preparation of a pyridine-annulated cycloheptadiene tricycle that promises to be a general strategy to access a variety of seven-membered ring containing natural products.

Cross-metathesis functionalized exo-olefin derivatives of lactide

Poly(lactic acid) is at the forefront of research into alternative replacements to fossil fuel derived polymers, yet preparation of derivatives of this key biodegradable polymer remain challenging. This article explores the use of two derivatives of lactide, each of which features an exocyclic olefin, and their pre-polymerization modification by olefin cross-metathesis. Methylenation of lactide with Tebbe’s reagent generates a novel 5-methylenated lactide monomer, (3S,6S)-3,6-dimethyl-5-methylene-1,4-dioxan-2-one, complementing the previously reported 3-methylenated (6S)-3-methylene-6-methyl-1,4-dioxan-2,5-dione. While ring-opening of each monomer is not productive, olefin cross-metathesis can be used to functionalize each of the exocyclic olefins to produce a family of monomers. The ring-opening polymerization of these new monomers, and their hydrogenated congeners, is facilitated by organo- and Lewis-acid catalysts. Together, they offer a new strategy for derivatizing and altering the properties of poly(lactic acid).
