Concise syntheses of the natural products (+)-sylvaticin and (+)-cis-sylvaticin

Two concise syntheses of the natural products cis-sylvaticin and sylvaticin are reported, using oxidative cyclization methodology as the key step. A sequential solvolysis/hydride shift/intramolecular reduction cascade was used to establish the trans stereochemistry of one of the THF rings of sylvaticin.

The synthesis and characterization of ruthenium complexes containing polypyridine ligands: Ru(dppz)(PPh3)2Cl2, Ru(bpy)(PPh3)2Cl2, Ru(phen)(PPh 3)2Cl2, Ru(dppz-Cl)(PPh3) 2Cl2, Ru(phen)(CO)2Cl2, Ru(bpy)(CO)2Cl2 and Ru(dppz)(CO)2Cl2 (where dppz: dipyrido[3,2-a:2?,3?-c]phenazine, dppz-Cl: 10-chlororodypirido[3,2-a:2?,3?-c]phenazine, phen: 1,10-phenanthroline and bipy: 2,2?-bipyridine) are reported. The ruthenium complexes show high activity as catalysts in the hydrogenation reaction of N-benzylideneaniline and the hydrogen transfer reaction. The products of the catalysis were obtained with conversions between 21 and 91% after 2 h of reaction. The Ru(phen)(CO)2Cl2 complex was the catalyst that showed the highest conversion (91%) for the hydrogenation of N-benzylideneaniline. The complexes Ru(dppz)(PPh3)2Cl 2, Ru(bpy)(PPh3)2Cl2 and Ru(dppz)(CO)2Cl2 showed 99% conversion in the hydrogen transfer reaction.

Enzymatic diastereo- and enantioselective synthesis of alpha-alkyl- alpha,beta-dihydroxyketones

An enzymatic strategy for the preparation of optically pure alpha-alkyl-alpha,beta-dihydroxyketones is reported. Homo- and cross-coupling reactions of alpha-diketones catalyzed by acetylacetoin synthase (AAS) produce a set of alpha-alkyl-alpha-hydroxy-beta-diketones (30-60%, ee 67-90%), which in turn are reduced regio-, diastereo-, and enantioselectively to the corresponding chiral alpha-alkyl-alpha,beta- dihydroxyketones (60-70%, ee >95%) using acetylacetoin reductase (AAR) as catalyst. Both enzymes are obtained from Bacillus licheniformis and used in a crude form. The relative syn stereochemistry of the enantiopure alpha,beta-dihydroxy products is assigned by NOE experiments, whereas their absolute configuration is determined by conversion of the selected 3,4-dihydroxy-3-methyl-pentan-2-one to the natural product (+)-citreodiol.

Dendritic tetranuclear Ru(II) complexes based on the nonsymmetrical PHEHAT bridging ligand and their building blocks: Synthesis, characterization, and electrochemical and photophysical properties

Dinuclear and tetranuclear Ru(II) compounds 1, 2, 3, and 4 based on the PHEHAT ligand (PHEHAT = 1,10-phenanthrolino[5,6-b]-1,4,5,8,9,12- hexaazatriphenylene) are prepared and characterized on the basis of the data for other related mononuclear species. Their electrochemical and spectroscopic behaviors are discussed. The nonspectroelectrochemical correlation obtained for 1, 2, 3, and 4 is explained on the basis of these data. From the behavior in emission, it is concluded that the internal energy transfer takes place from the core to the peripheral metallic units in 3 and 4.

Reduction of the cation <(eta5-C5H5)Fe(tripod)>PF6 with lithium aluminium hydride gives (eta5-C5H5)FeH(tripod) via an SN1 mechanism, involving prior dissociation of a phosphine ligand leading to direct attack of hydride on the metal, in contrast with the related ruthenium cations <(eta5-C5H5)RuL3>PF6 (L3 = triphos or tripod) which give the cyclopentadiene complexes (eta4-C5H6)RuL3 via exo-hydride attack on the cyclopentadienyl ligand .

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.HPLC of Formula: C41H35ClP2Ru, you can also check out more blogs about32993-05-8

Neutral chiral cyclopentadienyl Ru(ii)Cl catalysts enable enantioselective [2+2]-cycloadditions

Cyclopentadienyl ruthenium(ii) complexes with a large number of available coordination sites are frequently used catalysts for a broad range of transformations. To be able to render these transformations enantioselective, we have designed a chiral neutral CpxRu(ii)Cl complex basing on an atropchiral cyclopentadienyl (Cpx) ligand which is accessed in a streamlined C-H functionalisation approach. The catalyst displays excellent levels of reactivity and enantioselectivity for enantioselective [2+2]-cycloadditions leading to strained chiral cyclobutenes, allowing for catalyst loadings as low as 1 mol%. A very strong counterion effect of a bound chloride anion transforms the corresponding unselective cationic complex into a highly enantioselective neutral version. Moreover, by adding norbornadiene at the end of the reaction the catalyst can be recovered and subsequently reused.

A Relay Strategy Actuates Pre-Existing Trisubstituted Olefins in Monoterpenoids for Cross-Metathesis with Trisubstituted Alkenes

A retrosynthetic disconnection-reconnection analysis of epoxypolyenes – substrates that can undergo cyclization to podocarpane-type tricycles – reveals relay-actuated Delta6,7-functionalized monoterpenoid alcohols for ruthenium benzylidene catalyzed olefin cross-metathesis with homoprenyl benzenes. Successful implementation of this approach provided several epoxypolyenes as expected (E/Z, ca. 2-3:1). The method is further generalized for the cross-metathesis of pre-existing trisubstituted olefins in other relay-actuated Delta6,7-functionalized monoterpenoid alcohols with various other trisubstituted alkenes to form new trisubstituted olefins. Epoxypolyene cyclization of an enantiomerically pure, but geometrically impure, epoxypolyene substrate provides an enantiomerically pure, trans-fused, podocarpane-type tricycle (from the E-geometrical isomer).

Novel platinum group metal complexes bearing bidentate chelating pyrimidyl-NHC and pyrimidyl imidazolyl-thione ligands: Syntheses, spectral and structural characterization

A family of novel platinum group metal complexes containing bidentate chelating 1-pyrimidyl-3-methylimidazolyl bromide (HL1¡¤Br) and 1-pyrimidyl-3-methylimidazolyl-2-thione (L2) ligands has been synthesized. The synthetic protocol for the formation of these complexes differs from one ligand to the other. Treatment of ligand (HL1¡¤Br) with the metal precursors led to the formation of complexes via in situ carbene transfer reactions. The silver-NHC complex (1) was formed by the reaction of HL1¡¤Br with silver oxide under light-free conditions. Subsequent addition of appropriate metal precursors to the silver-NHC complex yielded [(eta6-arene)Ru(L1)Cl] PF6 complexes {arene = C6H6 (2), p- iPrC6H4Me (3), C6Me6 (4)} on stirring at room temperature, whereas the complexes [CpRu(L1)(PPh 3)]PF6 {Cp = C5H5 (5), C 9H7 (6)} were obtained under reflux conditions. In the case of ligand L2, stirring of equimolar quantities of metal precursors and the ligand at room temperature yielded [(eta6-arene)Ru(L2)Cl]PF 6 {arene = C6H6 (7), p-iPrC 6H4Me (8), C6Me6 (9)}, and [Cp*M(L2)Cl]PF6 {Cp* = C5Me5, M = Rh (10), Ir (11)}. All these complexes were characterized by CHN analysis, IR, NMR and mass spectrometry besides confirmation by single crystal X-ray diffraction studies for some representative complexes as their hexafluorophosphate salts [3]PF6, [5]PF6, [8]PF 6 and [10]PF6.
