Metathesis-based de novo synthesis of noviose

The rare carbohydrate L-(+)-noviose was synthesized from enantiomerically pure L-lactate. The configuration at C-4 was established by diastereoselective nucleophilic addition to an in-situ-generated lactaldehyde. The resulting homoallylic alcohol was further transformed into a set of ring-closing metathesis (RCM) precursors. These compounds were converted into noviose in few steps using RCM and RCM-allylic-oxidation sequences. S-Ethyl lactate was converted into an enantiomerically pure tertiary homoallylic alcohol, which was then transformed into noviose using olefin metathesis reactions. Copyright

Evidence that I”S? Controls Interfacial Electron Transfer Dynamics from Anatase TiO2 to Molecular Acceptors

Recombination of electrons injected into TiO2 with molecular acceptors present at the interface represents an important loss mechanism in dye-sensitized water oxidation and electrical power generation. Herein, the kinetics for this interfacial electron transfer reaction to oxidized triphenylamine (TPA) acceptors was quantified over a 70 temperature range for para-methyl-TPA (Me-TPA) dissolved in acetonitrile solution, 4-[N,N-di(p-tolyl)amino]benzylphosphonic acid (a-TPA) anchored to the TiO2, and a TPA covalently bound to a ruthenium sensitizer, [Ru(tpy-C6H4-PO3H2)(tpy-TPA)]2+ “RuTPA”, where tpy is 2,2?:6?,2??-terpyridine. Activation energies extracted from an Arrhenius analysis were found to be 11 ¡À 1 kJ mol-1 for Me-TPA and 22 ¡À 1 kJ mol-1 for a-TPA, values that were insensitive to the identity of different sensitizers. Recombination to RuTPA+ proceeded with Ea = 27 ¡À 1 kJ mol-1 that decreased to 19 ¡À 1 kJ mol-1 when recombination occurred to an oxidized para-methoxy TPA (MeO-TPA) dissolved in CH3CN. Eyring analysis revealed a smaller entropy of activation |I”S?| when the a-TPA was anchored to the surface or covalently linked to the sensitizer, compared to that when Me-TPA was dissolved in CH3CN. In all cases, Eyring analysis provided large and negative I”S? values that point toward unfavorable entropic factors as the key contributor to the barrier that underlies the slow recombination kinetics that are generally observed at dye-sensitized TiO2 interfaces.

Synthesis of phenanthroline derivatives by Sonogashira reaction and the use of their ruthenium complexes as optical sensors

The phenanthroline derivatives, which have alkynyl groups, were synthesized by palladium-catalyzed, Sonogashira cross-coupling reaction to provide the following coupled products: 4,7-bis(4-phenylethynyl-phenyl)-[1,10]phenanthroline (6a) and 4,7-bis{4-(4-hydroxy-buty-1-ynyl)-phenyl)-[1,10]phenanthroline (6b) at 87 and 89% yield, respectively. Their ruthenium complexes, tris{4,7-bis(4-phenylethynyl-phenyl)-[1,10]phenanthroline} ruthenium(II) bis(hexafluorophosphate) (7a) and tris[4,7-bis{4-(4-hydroxy-buty-1-ynyl)-phenyl)-[1, 10]phenanthroline}ruthenium(II)bis(hexafluoro-phosphate) (7b), were synthesized under mild conditions. The former showed relative fluorescence intensity changes between fully oxygenated and fully deoxygenated atmospheres, while the latter showed a linear fluorescence intensity response between pH 6 and 13.

Pd and Ru complexes bearing axially chiral ligands for the asymmetric hydrogenation of C=C and C=O double bonds

Complexes composed of either Pd or Ru as central metal and ligands with axial chirality in all cases were used as hydrogenation catalysts. The ligands were (R)- and (S)-6,6?-dimethyl-2,2?-diaminobiphenyl, (R)-(+)-1-1?-Bi(2-naphtylamine), (R)-2,2?-Bis(diphenylphosphino)-1, 1?-binaphthalene and (R)-2,2?-Bis(di-p-tolylphosphino)-1,1?- binaphthyl. The Pd(II) complexes had one diamine ligand and the Ru(II) complexes had one bisphosphine and one diamine ligand, forming seven member chelate rings with the metal center. The pro-chiral substrates used were itaconic acid, alpha-acetamidocinnamic acid and acetophenone. The Pd complexes showed 100% chemoselectivity toward the CC bond, and toward the CO bond in the case of Ru. The yield and enantiomeric excess versus time behavior was studied using a large substrate/catalyst ratio. The addition of an organic base to the reaction with Pd complexes enhanced yield and enantiomeric excess. Use of the (S)-diamine ligand in the complex favored the (R)-products. The best results with itaconic acid were 61% yield and 56% enantiomeric excess and 55% yield and 52% enantiomeric excess with alpha-acetamidocinnamic acid, both catalyzed by Pd(OCOCF3)2 ((S)-6,6?-dimethyl-2,2?- diaminobiphenyl) in 2,2,2-trifluoroethanol. In the case of the Ru catalysts, (S)-1-phenylethanol formed preferentially during hydrogenation of acetophenone. Potassium tert-butoxide stabilized the enantiomeric excess. The best result was 87% yield and 41% enantiomeric excess catalyzed by ((R)-2,2?-Bis(di-p- tolylphosphino)-1,1?-binaphthyl)-RuCl2-((R)-(+)-1-1?- Bi(2-naphtylamine)).

Enantioselective total synthesis of FD-891

The enantioselective synthesis of FD-891 has been achieved with a longest linear sequence of 21 steps. The synthetic strategy involves the use of aldol additions of a chlorotitanium enolate of N-acylthiazolidinethiones as the key reaction to establish 6 of the 10 stereogenic centers. A key cross-metathesis and a late-stage Julia olefination serve to assemble three key subunits. Copyright

Syntheses of Chelating Tetrazole-Containing Ligands and Studies of Their Palladium(II) and Ruthenium(II) Complexes

Eleven chelating tetrazole-containing ligands have been synthesized, and their complexes with palladium(II) and ruthenium(II) prepared.Proton n.m.r. spectroscopy, electronic absorption spectroscopy and cyclic voltammetry have been used to study the nature of the metal-ligand interactions in these complexes.The negatively charged tetrazolate group is shown to be a strong electron donor with very different properties to those of the protonated or alkylated tetrazole group.This leads to pH control of the properties of transition metal complexes containing such ligands.

Specific reactivity of SH versus OH functions towards dinuclear arene ruthenium units: Synthesis of cationic complexes of the type [(arene)2Ru2(SR)3]+

The reaction of [(arene)RuCl2]2 (arene = C6H6, p-Me-C6H4-iPr, C6Me6) with p-thiocresol, 2-mercaptoethanol and p-mercaptophenol in refluxing ethanol gives the tris-thiolato complexes [(arene)2Ru2(SR)3]+ (R =p-C6H4-Me, CH2CH2OH, p-C6H4OH) which can be isolated as the chloride salts. The remarkable selectivity of (arene)ruthenium units for SH versus OH functions reflects the affinity of ruthenium towards sulfur.
