A strategy for the synthesis of functionalized indenes is presented. The readily available substituted phenols are used as starting materials in the reaction sequence composed of Pd-catalyzed Suzuki coupling and Ru-catalyzed ring-closing metathesis, thus representing a practical method for the controlled construction of functionalized indene derivatives. The methodology has been successfully applied to a broad range of substrates, producing substituted indenes in excellent yields. This approach is also utilized for the synthesis of substituted indenes selectively deuterated in position 3, which are rare in literature.

Two complex norditerpenoids, caribenols A and B, were accessed from a common building block. Our synthesis of caribenol A features the diastereoselective formation of the seven-membered ring through a Friedel-Crafts triflation and a late-stage oxidation of a furan ring. The first synthesis of caribenol B was achieved using an intramolecular organocatalytic alpha-arylation. An unusual intramolecular aldol addition was developed for the assembly of its cyclopentenone moiety, and the challenging trans-diol moiety was installed through a selective nucleophilic addition to a hydroxy 1,2-diketone. Our overall synthetic strategy, which also resulted in a second-generation synthesis of amphilectolide, confirms the usefulness of furans as powerful nucleophiles and versatile synthons.

In our search for more-selective olefin metathesis catalysts, a series of Hoveyda-Grubbs-type second-generation complexes bearing unsymmetrical N-heterocyclic carbene (NHC) ligands were synthesized and tested in model reactions. It was found that the N-benzyl substituent in NHC has a positive influence on the selectivity of the newly obtained catalysts in the self-metathesis reaction of alpha-olefins. As expected, a typical relationship between activity and selectivity with respect to the N-aryl substituent used was observed. Dipp-containing complexes exhibited higher stability at elevated temperature, while Mes-bearing complexes typically gave better yields than their Dipp analogues.

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., Related Products of 301224-40-8

A new 18-electron ruthenium complex, where ruthenium catalytic center is coordinated with the N-mesitylimidazole and nitrate ligands, as well as o-isopropoxystyrene moiety, is reported. The synthesis and detailed characterization of the Ru complex, together with density functional theory calculations (DFT), are presented. The complex is air- and moisture-stable, although has weak catalytical activity in the model metathesis reactions. However, its activity increases upon the addition of an aqueous HCl 1 M solution. Activated Ru complex successfully promotes metathesis in organic solvents as well as in water, enabling efficient performance (even up to 100%) of the catalyst under environment-friendly conditions. The activation mechanism of the reported catalyst is supported by time-dependent DFT calculations and ab initio molecular dynamics simulations.

The build/couple/pair strategy has yielded small molecules with stereochemical and skeletal diversity by using short reaction sequences. Subsequent screening has shown that these compounds can achieve biological tasks considered challenging if not impossible (‘undruggable’) for small molecules. We have developed gold(I)-catalyzed cascade reactions of easily prepared propargyl propiolates as a means to achieve effective intermolecular coupling reactions for this strategy. Sequential alkyne activationof propargyl propiolates by a cationic gold(I) catalyst yields an oxoca rbenium ion that we previously showed is trapped by C-based nucleophilesat an extrannular site to yield alpha-pyrones. Here, we report O-base d nucleophiles react by ring opening to afford a novel polyfunctional product. In addition, by coupling suitable building blocks, we subsequently performed intramolecular pairing reactions that yield diverse and complex skeletons. These pairing reactions include one based on a novel aza-Wittig-6?-electrocyclization sequence and others based on ring-closing metathesis reactions.

Exquisite control of catalytic metathesis reactivity is possible through ligand-based variation of ruthenium carbene complexes. Sterically hindered alkenes, however, remain a generally recalcitrant class of substrates for intermolecular cross-metathesis. Allylic chalcogenides (sulfides and selenides) have emerged as ?privileged? substrates that exhibit enhanced turnover rates with the commercially available second-generation ruthenium catalyst. Increased turnover rates are advantageous when competing catalyst degradation is limiting, although specific mechanisms have not been defined. Herein, we describe facile cross-metathesis of allylic sulfone reagents with sterically hindered isoprenoid alkene substrates. Furthermore, we demonstrate the first example of intermolecular cross-metathesis of ruthenium carbenes with a tetrasubstituted alkene. Computational analysis by combined coupled cluster/DFT calculations exposes a favorable energetic profile for metallacyclobutane formation from chelating ruthenium beta-chalcogenide carbene intermediates. These results establish allylic sulfones as privileged reagents for a substrate-based strategy of cross-metathesis derivatization.
