Total Synthesis of Solandelactones A and B

The total synthesis of solandelactones A and B is presented. The eastern cyclopropyl moiety was prepared following an exceptionally short chemoenzymatic approach whereas enantioselective synthesis of the western side-chain relied on the application of diastereomerically pure allyl boronates. The natural products solandelactones A and B were isolated in good overall yields following convergence of each eastern and western element by application of the Nozaki-Hiyama-Kishi reaction.

Amine synthesis via carbonylation reactions: Aminomethylation

The preparation of aliphatic amines and alicyclic diamines by reaction of olefins, synthesis gas and dimethylamine, known as aminomethylation, was investigated. Synthesis involves homogeneous rhodium and ruthenium catalysts or mixtures thereof at very low concentrations. Employing 3-12 ppm Rh and 50- 100 ppm Ru results in up to 97% selectivity towards the amines at conversions of up to 98% if aliphatic mono-olefins are used as starting materials. At high catalyst concentrations (173 ppm Rh, 2660 ppm Ru) the corresponding diamine is obtained from dicyclopentadiene in 89% yield. The influence of reaction parameters and catalyst ratios on the n/i-selectivity of the product indicates the scope as well as the limits of such a multi-step synthesis for a commercial process.

Methanol electro-oxidation at Ptx Ru(1-x)O y electrodes – An in situ FTIR study

In this work we investigated the nature of the intermediates adsorbed during the electrooxidation of methanol on PtxRu (1-x)Oy electrodes, where 0.5 < x < 0.9, prepared by the decomposition of polymeric precursors. Thin layer electrodes with different compositions were prepared directly on a gold substrate by thermal decomposition of ethylene glycol - citric acid solutions containing the precursor salts at 400C. In situ IR reflectance spectra were obtained using the SPAIRS (single potential alteration infrared reflectance spectroscopy) and SNIFTIRS (subtractively normalized interfacial Fourier transform IR reflectance spectroscopy) techniques. For all the investigated compositions, the SNIFTIRS and SPAIRS spectra displayed three main bands, which were attributed to CO species in the linear (COL) and bridged (COB) forms adsorbed over Pt and linearly adsorbed over Ru. Formation of CO2 carbonyl species was also detected. The spectra features were analyzed in terms of the applied potential and they were compared with those reported for Pt-Ru electrodes prepared by other methods. The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 10049-08-8 is helpful to your research., Computed Properties of Cl3Ru

Synthesis and characterisation of unsymmetrical metal (Ru11, Os”) and ferrocenyl complexes of l,3,5-triethynylbenzene

A series of complexes featuring metal (/ra;w-[RuCl(dppm)2], fra/-[OsCl(dppm)J or [Ru(r)-CjHs)(PPh3)2]) and ferrocenyl (C5H5FeC5H4) units unsymmetrically arranged around the periphery of a 1,3,5-triethynylbenzene core have been synthesized in good to reasonable yields by various synthetic routes. A crystal structure determination of/ra//5-[(C5HjFeC5H4OC)2C6Hj{OCRu(dppm)2CI}] shows that the two ferrocenyl units are positioned on the same side of the trisubstituted aromatic core and that all three ethynyl linkages are bent ‘down’ out of the plane of the central ring. Electrochemical studies show that in the heteronuclear coupling of osmium(n) or ruthenium(n) fragment(s) with ferrocenyl unit(s) the oxidation of Os” or Ru” precedes that of the ferrocene unit(s). In addition, whereas in diruthenium or diosmium complexes the oxidation of the two metal centres proceeds separately, in the diferrocenyl complexes the oxidation of the two ferrocene units occurs at the same potential values. This result shows that on appending different groups to the same skeletal core (namely, triethynylbenzene) some can interact electronically (the Ru”- and Os”-containing fragments) whereas others do not (the ferrocenyl units).

Concise synthesis of broussonone A

A concise and expeditious approach to the total synthesis of broussonone A, a p-quinol natural compound, has been developed. The key features of the synthesis include the Grubbs II catalyst mediated cross metathesis of two aromatic subunits, and a chemoselective oxidative dearomatizationin the presence of two phenol moieties. Especially, optimization associated with the CM reaction of ortho-alkoxystyrenes was also studied, which are known to be ineffective for Ru-catalyzed metathesis reactions under conventional reaction conditions because ortho-alkoxy group could coordinate to the ruthenium center, resulting in the potential complication of catalyst inhibition.
