Ruthenium metathesis catalysts with saturated unsymmetrical N-heterocyclic carbene ligands

The facile synthesis of two new unsymmetrical N-heterocyclic carbene (NHC) ligands from commercially available monosubstituted diamines is presented. The resultant unsymmetrical NHC ligands have been complexed to ruthenium to give novel olefin metathesis initiators. Of particular interest, the new complexes (7a and 8a) gave significantly different E:Z ratios in cross-metathesis reactions and gave an improved selectivity in diastereoselective ring-closing metathesis, in comparison to the corresponding Grubbs 2 (2) and Hoveyda – Grubbs (3) complexes.

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 246047-72-3 is helpful to your research., Synthetic Route of 246047-72-3

Asymmetric synthesis of a chiral buckybowl, trimethylsumanene

The first asymmetric synthesis of a chiral buckybowl, a C3 symmetric (C)-8,13,18-trimethylsumanene (1), was achieved by employing a synthetic strategy that translates chirality at sp3 centers into bowl chirality. The synthesis features a syn selective cyclotrimerization of an enantiopure halonorbornene derivative, tandem ring-opening/closing olefin metathesis reactions, and DDQ oxidation at low temperature. The bowl-to-bowl inversion energy of 1 was determined as 21.6 kcal/mol by circular dichroism spectra measurement. Copyright

Fast-initiating, ruthenium-based catalysts for improved activity in highly E-selective cross metathesis

Ruthenium-based olefin metathesis catalysts bearing dithiolate ligands have been recently employed to generate olefins with high E-selectivity (>99% E) but have been limited by low to moderate yields. In this report, 1H NMR studies reveal that a major contributing factor to this low activity is the extremely low initiation rates of these catalysts with trans olefins. Introducing a 2-isopropoxy-3-phenylbenzylidene ligand in place of the conventional 2-isopropoxybenzylidene ligand resulted in catalysts that initiate rapidly under reaction conditions. As a result, reactions were completed in significantly less time and delivered higher yields than those in previous reports while maintaining high stereoselectivity (>99% E).

Asymmetric total synthesis of (-)-mangiferaelactone by using an appropriately substituted thiophene as a masked synthon for C-alkyl glycoside

Abstract Asymmetric total synthesis of naturally occurring nonenolide (-)-mangiferaelactone was attempted through RCAM (ring closing alkyne metathesis) reaction. As the attempted RCAM reaction failed, the synthesis was finally achieved by successful exploration of a ring closing metathesis (RCM) reaction. 2-Propylthiophene was used as a masked synthon for n-heptyl glycoside, which served as main source for one of the RCM precursors and accessed by reductive desulfurization (Mozingo type reduction) of an appropriately substituted thiophene ribofuranoside. The other RCM precursor was accessed by applying an enzymatic kinetic resolution/Mitsunobu inversion sequence to an alkyne alcohol.

18-electron ruthenium phosphine sulfonate catalysts for olefin metathesis

The first instances of ruthenium alkylidene complexes based on chelating phosphine sulfonates are presented. Although these complexes are formally 18-electron complexes bearing cis phosphines and cis one-electron donors (sulfonates and chlorides), they are surprisingly active for ring-closing metathesis, cross-metathesis, and ring-opening metathesis polymerization, thus highlighting the unique potential of the sulfonate ligand in the design of a ruthenium metathesis catalyst.

Enantioselective Total Synthesis of Antibiotic CJ-16,264, Synthesis and Biological Evaluation of Designed Analogues, and Discovery of Highly Potent and Simpler Antibacterial Agents

An improved and enantioselective total synthesis of antibiotic CJ-16,264 through a practical kinetic resolution and an iodolactonization reaction to form the iodo pyrrolizidinone fragment of the molecule is described. A series of racemic and enantiopure analogues of CJ-16,264 was designed and synthesized through the developed synthetic technologies and tested against drug-resistant bacterial strains. These studies led to interesting structure-activity relationships and the identification of a number of simpler, and yet equipotent, or even more potent, antibacterial agents than the natural product, thereby setting the foundation for further investigations in the quest for new anti-infective drugs.

Ruthenium alkylidenes: Fast initiators for olefin metathesis

A family of ruthenium alkylidene complexes, (H2IMes)RuCl 2(=CHR)(3-bromopyridine)2, where R = Me, Et, nPr, as well as the corresponding PCys complexes, (H2IMes)RuCl2(=CHR) (PCy3), have been prepared. The PCys alkylidene complexes exhibit much higher stoichiometric reactivity than does the analogous benzylidene complex, reflecting faster dissociation of PCy3 from the alkylidene complexes.

Direct synthesis of soluble, end-functionalized polyenes and polyacetylene block copolymers

The ring-opening metathesis polymerization (ROMP) of 1,3,5,7-cyclooctatetraene (COT) in the presence of a chain transfer agent (CTA) with a highly active ruthenium olefin metathesis catalyst resulted in the formation of soluble polyenes. Small molecule CTAs containing an internal olefin and a variety of functional groups resulted in soluble telechelic polyenes with up to 20 double bonds. Use of polymeric CTAs with an olefin terminus resulted in polyacetylene block copolymers. These materials were subjected to a variety of solution and solid phase characterization techniques including 1H NMR, UV/vis, and FT-IR spectroscopies, as well as MALDI-TOF MS and AFM.
