Facile synthesis of effcient and selective ruthenium olefin metathesis catalysts with sulfonate and phosphate ligands

A series of novel, air-stable ruthenium NHC catalysts with sulfonate and phosphate anions have been prepared easily in one pot at high yields using commercially available precursors. The catalysts were found to be effective for ring-opening metathesis polymerization, ring-closing metathesis, and cross-metathesis. The catalysts showed higher cis-selectivity in olefin cross-metathesis reactions as compared to earlier known ruthenium-based olefin metathesis catalysts, with allylbenzene and cis-1,4-diacetoxybutene as substrates.

Total Synthesis of the Proposed Structure of Penasulfate A: L -Arabinose as a Source of Chirality

The total synthesis of putative penasulfate A was effectively achieved by a convergent strategy with a longest linear sequence of 14 steps and overall yield of 8.6%. The highlights of our strategy involved an E-selective olefin cross-metathesis, Suzuki cross-coupling, and a copper(I)-catalyzed coupling reaction.

Synthesis and characterization of ruthenium(II) complexes with dendritic N-heterocyclic carbene ligands Metallodendrimers Special Issue

Ru(II) complexes with a N-heterocyclic carbene ligand bearing flexible zeroth-, first-, or second-generation dendritic moieties were synthesized and characterized. The structure of the ruthenium complex with the zeroth-generation dendritic moieties was determined by X-ray crystallography. ONIOM calculations showed that the second generation dendritic moieties surrounded the ruthenium core. These complexes worked as active catalysts for the ring-closing metathesis at 25 C.

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

Activation of olefin metathesis complexes containing unsymmetrical unsaturated N-heterocyclic carbenes by copper and gold transmetalation

The activation of ruthenium-indenylidene complexes containing two unsymmetrical unsaturated N-heterocyclic carbenes (u2-NHCs) by a transmetalation process is reported. The use of copper(i) or gold(i) chlorides promotes the rapid trapping of one NHC ligand, which releases the catalytically active Ru-species. Impressive initiation rates with full-conversions are observed within one minute. This practical protocol demonstrates excellent catalytic performances in various ring-closing metathesis (RCM) and self-metathesis (SM) reactions.

Conducting Olefin Metathesis Reactions in Air: Breaking the Paradigm

The first study of low catalyst loading olefin metathesis reactions in air is reported. TON values of up to 7000 were obtained using nondegassed solvents with commercially available precatalysts Caz-1, Hov-II, and Ind-II. The simple experimental conditions allow olefin metathesis reactions to be carried out on the benchtop using technical grade solvents in air. (Chemical Equation Presented).

Kinetic selectivity of olefin metathesis catalysts bearing cyclic (alkyl)(amino)carbenes

The evaluation of ruthenium olefin metathesis catalysts 4-6 bearing cyclic (alkyl)(amino)carbenes (CAACs) in the cross-metathesis of cis-1,4-diacetoxy-2- butene (7) with allylbenzene (8) and the ethenolysis of methyl oleate (11) is reported. Relative to most NHC-substituted complexes, CAAC-substituted catalysts exhibit lower E/Z ratios (3:1 at 70% conversion) in the cross-metathesis of 7 and 8. Additionally, complexes 4-6 demonstrate good selectivity for the formation of terminal olefins versus internal olefins in the ethenolysis of 11. Indeed, complex 6 achieved 35 000 TONs, the highest recorded to date. CAAC-substituted complexes exhibit markedly different kinetic selectivity than most NHC-substituted complexes.

Regio- and Diastereoselective Functionalization of 3-Amino-hexahydrooxazoninones

The regio- and diastereoselectivity of transformations of nine-membered lactams with a Z double bond in the cyclic tether towards building blocks for medicinal chemistry was evaluated. To this end, 3-aminohexahydrooxazoninones were synthesized using a standard ring-closing metathesis (RCM) approach of easily available O,N-bisallylated serine derivatives. The obtained Z double bond in the medium sized lactam was used as a handle to evaluate the stereoselectivity of electrophile induced transformations. It was shown that dibromination and electrophilic activation by NBS followed by attack of O-nucleophiles proceeded in a diastereoselective manner. Cyclization of obtained bromohydrins and face-selective epoxidation gave access to both diastereomers of the epoxidized lactams. Finally, a Heck-reaction of a bromobenzyl moiety at the lactam N-atom with the Z-double bond resulted in the diastereoselective formation of bicyclic bridged nine-membered lactams.

Asymmetric synthesis of (+)-polyanthellin A

(Chemical Equation Presented) A concise and convergent route to (+)-polyanthellin A is presented. This synthesis features a diastereoselective cyclopropane/aldehyde [3+2] cycloaddition to install the hydroisobenzofuran core. The use of MADNTf2 as a potent, bulky Lewis acid was essential to allow a labile beta-silyloxy aldehyde to be used in the cycloaddition. Other key steps include a ring-closing metathesis and a selective olefin oxidation.

Synthetic studies on Stemona alkaloids. Construction of the sessilifoliamides B and C and 1,12-secostenine skeleton

An original synthetic approach to the Stemona alkaloids stenine and sessilifoliamides B and C has been explored. The strategy relies on the early construction of the pyrroloazepine core (rings A and B) and latter addition of the furanone (ring D) and ethyl chain at C-10, which are the common structural features of the three alkaloids. The formation of the azabicyclic nucleus through an intramolecular Morita-Baylis-Hillman reaction of a properly substituted pyrrolidone has been extensively investigated by modifications on the substrate and all the parameters involved in the process and an efficient protocol in terms of yield and stereoselectivity has been developed. Despite many alternative tactics were explored, insurmountable difficulties found in the last synthetic steps have frustrated the completion of the syntheses. However, along the way, a plethora of new compounds was prepared, some of them containing the full skeleton of the targeted alkaloids, which can be useful for future synthetic applications.
