Z – And enantioselective ring-opening/cross-metathesis with enol ethers catalyzed by stereogenic-at-Ru carbenes: Reactivity, selectivity, and Curtin-Hammett kinetics

The first instances of Z- and enantioselective Ru-catalyzed olefin metathesis are presented. Ring-opening/cross-metathesis (ROCM) reactions of oxabicyclic alkenes and enol ethers and a phenyl vinyl sulfide are promoted by 0.5-5.0 mol % of enantiomerically pure stereogenic-at-Ru complexes with an aryloxy chelate tethered to the N-heterocyclic carbene. Products are formed efficiently and with exceptional enantioselectivity (>98:2 enantiomer ratio). Surprisingly, the enantioselective ROCM reactions proceed with high Z selectivity (up to 98% Z). Moreover, reactions proceed with the opposite sense of enantioselectivity versus aryl olefins, which afford E isomers exclusively. Preliminary DFT calculations in support of Curtin-Hammett kinetics as well as initial models that account for the stereoselectivity levels and trends are provided.

Ring-Closing Enyne Metathesis of Terminal Alkynes with Propargylic Hindrance

The ring closing enyne metathesis of substrates with propargylic hindrance was investigated, revealing the successful combination of the Stewart-Grubbs catalysts and microwave heating sometimes up to 170 C for oxacycles. Medium-sized rings were obtained from terminal alkynes previously reputed as reluctant substrates. This unmatched combination was applied to the synthesis of carbocycles and oxacycles. In addition, this is the first report on the use of the Stewart Grubbs catalyst in ring closing enyne metatheses. (Figure Presented).

Cross metathesis of several methylenecyclopentane derivatives

The cross metathesis (CM) of several methylenecyclopentane derivatives using Hoveyda-Grubbs second generation catalyst 4 (5-10 mol %) has been studied. Medium to good yields of tetrasubstituted alkenes have been obtained. In the case of 8-methyl-2,5-dimethylene-2,3,5,6-tetrahydro-1H,4H-3a,6a- (methanoiminomethano)pentalene-7,9-dione 2 products from single, double and triple CM were formed. With 8-methyl-5-methylene-5,6-dihydro-3a,6a- (methanoiminomethano)pentalene-2,7,9(1H,3H,4H)-trione 3 a good yield of the CM product was obtained working at 140C in xylene for 3 d, showing the high thermal stability of this catalyst. In the CM of diene 2 and enone 3, the main products were always the anti-stereoisomers.

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.Computed Properties of C31H38Cl2N2ORu, you can also check out more blogs about301224-40-8

Highly selective SmI2?H2O-promoted radical cyclisation of five-membered lactones

Radicals formed by SmI2?H2O-mediated electron transfer to the carbonyl group of unsaturated five-membered lactones undergo diastereoselective cyclisation to give cyclohexane-1,4-diols. The use of HMPA as an additive with SmI2?H2O gave improved conversion and diastereoselectivity in the cyclisations.

A practical and highly active ruthenium-based catalyst that effects the cross metathesis of acrylonitrile

The highest initiation rate of any reported ruthenium-based catalyst was found for the new olefin-metathesis catalyst [(H2IMes)(3-Br-py)2(Cl)2Ru=CHPh] (1), which was synthesized in one step from commercially available reagents. Complex 1 is highly efficient for the cross metathesis of acrylonitrile, which is generally a poor substrate for metathesis reactions (e.g., see scheme). Mes = 2,4,6-trimethylphenyl.

Unified Synthesis of 10-Oxygenated Lycopodium Alkaloids: Impact of C10-Stereochemistry on Reactivity

The pronounced impact of the C10 stereochemistry on the successful construction of a polycyclic Lycopodium alkaloid scaffold has been explored. A wide range of reaction conditions and functionality were investigated to control a keto sulfone Michael addition to construct the C7-C12 linkage. An unexpected, overriding impact of the C10 stereochemistry in stereoselectivity and reaction rate in the Michael addition was observed. Furthermore, divergent reactivity of a conformationally accelerated, intramolecular Mannich cyclization based on the C10 stereochemistry was discovered. The successful execution of this synthetic route resulted in the total synthesis of all three known 10-oxygenated Lycopodium alkaloids: 10-hydroxylycopodine, paniculine, and deacetylpaniculine.

Enantio- and Diastereoselective 1,2-Additions to alpha-Ketoesters with Diborylmethane and Substituted 1,1-Diborylalkanes

The catalytic enantioselective synthesis of boronate-substituted tertiary alcohols through additions of diborylmethane and substituted 1,1-diborylalkanes to alpha-ketoesters is reported. The reactions are catalyzed by readily available chiral phosphine/copper(I) complexes and produce beta-hydroxyboronates containing up to two contiguous stereogenic centers in up to 99:1 e.r. and greater than 20:1 d.r. The utility of the organoboron products is demonstrated through several chemoselective functionalizations. Evidence indicates the reactions occur via an enantioenriched alpha-boryl-copper-alkyl intermediate.

Chemical synthesis enables biochemical and antibacterial evaluation of streptolydigin antibiotics

Inhibition of bacterial transcription represents an effective and clinically validated anti-infective chemotherapeutic strategy. We describe the evolution of our approach to the streptolydigin class of antibiotics that target bacterial RNA polymerases (RNAPs). This effort resulted in the synthesis and biological evaluation of streptolydigin, streptolydiginone, streptolic acid, and a series of new streptolydigin-based agents. Subsequent biochemical evaluation of RNAP inhibition demonstrated that the presence of both streptolic acid and tetramic acid subunits was required for activity of this class of antibiotics. In addition, we identified 10,11-dihydrostreptolydigin as a new RNAP-targeting agent, which was assembled with high synthetic efficiency of 15 steps in the longest linear sequence. Dihydrostreptolydigin inhibited three representative bacterial RNAPs and displayed in vitro antibacterial activity against S. salivarius. The overall increase in synthetic efficiency combined with substantial antibacterial activity of this fully synthetic antibiotic demonstrates the power of organic synthesis in enabling design and comprehensive in vitro pharmacological evaluation of new chemical agents that target bacterial transcription.
