From highly enantioselective catalytic reaction of 1,3-diynes with aldehydes to facile asymmetric synthesis of polycyclic compounds

(S)-1,1?-Binaphth-2-ol (BINOL) in combination with ZnEt2, Ti(OiPr)4, and biscyclohexylamine was found to catalyze the highly enantioselective (83-95% ee) addition of various 1,3-diynes to aldehydes of diverse structures. This method provides a convenient pathway to generate a number of optically active dienediynes as the acyclic precursors to polycyclic compounds. The chiral dienediynes undergo highly chemoselective Pauson-Khand (PK) cycloaddition in benzaldehyde by using [Rh(cod)Cl]2 as the catalyst in the presence of rac-BINAP. High diastereoselectivity (up to >20:1) has also been achieved with the chiral dienediyne substrates containing a bulky substituent adjacent to the chiral center. In the presence of the Grubbs II catalyst, ring-closing enyne metathesis of the PK cycloaddition products led to the formation of the desired 5,5,7- and 5,5,8-fused tricyclic compounds. Further highly diastereoselective Diels-Alder reaction of a 5,5,7-tricyclic compound with maleic anhydride produced a 5,5,7,6-polycyclic product. The asymmetric synthesis of polycyclic compounds from optically active dienediynes has established a novel and efficient synthetic route to the structural framework of many biologically significant molecules.

Atropselective Dibrominations of a 1,1?-Disubstituted 2,2?-Biindolyl with Diverging Point-to-Axial Asymmetric Inductions. Deriving 2,2?-Biindolyl-3,3?-diphosphane Ligands for Asymmetric Catalysis

On the 1H NMR timescale, 2,2?-biindolyls with (R)-configured (1-alkoxyprop)-2-yl, (1-hydroxyprop)-2-yl, or (1-siloxyprop)-2-yl substituents at C-1 and C-1? are atropisomerically stable at <0 C and interconvert at >30 C. A 2,2?-biindolyl (R,R)-17 a of that kind and achiral (!) brominating reagents gave the atropisomerically stable 3,3?-dibromobiindolyls (M)- and/or (P)-18 a at best atropselectively?because of point-to-axial asymmetric inductions?and atropdivergently, exhibiting up to 95 % (M)- and as much (P)-atropselectivity. This route to atropisomerically pure biaryls is novel and should extend to other substrates and/or different functionalizations. The dibromobiindolyls (M)- and (P)-18 a furnished the biindolyldiphosphanes (M)- and (P)-14 without atropisomerization. These syntheses did not require the resolution of a racemic mixture, which distinguishes them from virtually all biaryldiphosphane syntheses known to date. (M)- and (P)-14 acted as ligands in catalytic asymmetric allylations and hydrogenations. Remarkably, the beta-ketoester rac-25 c was hydrogenated trans-selectively with 98 % ee; this included a dynamic kinetic resolution.

Reactivity and electrochemical behavior of ruthenium dithiolene complexes with coordinatively unsaturated metal centers: Cycloaddition and dimerization reactions

The novel ruthenium dithiolene complexes [(arene)Ru{S2C 2(COOMe)2}] (arene = C6H6 (1a), C6H4(Me)(iPr) (1b), C6Me6 (1c)) were synthesized. The equilibrium between complex 1a and the corresponding dimer [(C6H6)Ru{S2C2(COOMe) 2}]2 (1a?) was confirmed in solution. The reaction of complex 1a with dimethyl- or diethylacetylene dicaboxylate gave the alkene-bridged adducts [(C6H6)Ru{S2C 2(COOMe)2}{C2(COOR)2}] (R = Me (2a), Et (3a)) as [2 + 2] cycloaddition products formally. The reactions of complex 1a with diazo compounds also gave the alkylidene-bridged adducts [(C 6H6)Ru{S2C2(COOMe) 2}(CHR)] (R = H (4a), SiMe3 (5a), COOEt (6a)) as [2 + 1] cycloaddition products. The electrochemical behavior of complex 1a was investigated. The reductant of complex 1a was a stable species for several minutes. The oxidant of complex 1a was very unstable; the cation 1a+ formed was immediately converted to the corresponding cationic dimer 1a?+. The cationic dimer 1a?+ was stable for several minutes, and it was rapidly and quantitatively converted to the neutral complex 1a when it was reduced.

Intramolecular monomer-on-monomer (MoM) Mitsunobu cyclization for the synthesis of benzofused thiadiazepine-dioxides

The utilization of a monomer-on-monomer (MoM) intramolecular Mitsunobu cyclization reaction employing norbornenyl-tagged (Nb-tagged) reagents is reported for the synthesis of benzofused thiadiazepine-dioxides. Facile purification was achieved via ring-opening metathesis (ROM) polymerization initiated by one of three metathesis catalyst methods: (i) free metathesis catalyst, (ii) surface-initiated catalyst-armed silica, or (iii) surface-initiated catalyst-armed Co/C magnetic nanoparticles.

Mechanism of carbon-nitrogen bond scission on unsupported transition metal sulfides

The reactivity of a series of amines with various structures and different numbers of hydrogen atoms on the carbon atoms in the alpha and beta position, with respect to the nitrogen atom, was examined on four transition metal sulfides, i.e. NbS3, MoS2, RuS2, and Rh2S3. It is shown that the reaction mechanism proceeds via an elimination or a nucleophilic substitution the relative importance of which depends on the structure of the substrate to be transformed and on the transition metal sulfides properties. NbS3 is the most active sulfide of the series for the elimination reaction due to its high acidity, but it is inactive for the nucleophilic substitution. On the other hand, the surface species of Rh2S3 can be involved in a nucleophilic substitution but not in an elimination reaction. The other sulfides of the series behave in between. These results clearly demonstrate that the catalysts intervene differently in the HDN mechanism. Moreover, for a given solid the structure of a nitrogen-containing molecule strongly affects the elementary steps of its transformation. Accordingly, a precise mechanistic study of the reactivity of a model molecule at the surface of a sulfide cannot be generalized to the overall HDN process which involves several types of molecules.

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.Product Details of 10049-08-8, you can also check out more blogs about10049-08-8

A by-product of such activation, an aryloxybenzylidene ruthenium(III) complex 17 have been independently synthesised by reacting 13 with C2Cl6. This unique complex was characterised by spectroscopic and electrochemical methods, and by X-ray crystallography.

One-pot synthesis of hydrous MnO2 nanowires for selective oxidative transformation of furfuryl alcohol

Hydrous MnO2 nanowires were easily synthesized by an one-pot synthesis with a simple hydrothermal method. As prepared hydrous MnO2 nanowires were characterized with scanning emission microscopy (SEM), transmit emission microscopy (TEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET). They showed a good catalytic activity with the suitable nano-size of 4-5 nm and morphology. The furfuryl alcohol was selected as a substrate and the reaction was carried out in a toluene solvent at 100 ? under the atmospheric pressure of oxygen. The hydrous MnO2 nanowire catalyst exhibited an excellent yield of furfural with the first-rate selectivity and conversion. The catalytic performance during recycle tests was also carried out and the catalyst showed a good mechanical strength with a negligible loss in the activity over five reaction cycles.

The effect of material purity on the optical and scintillation properties of solution-grown trans-stilbene crystals

Large, 10 cm-size, single crystals of trans-stilbene were grown for the first time from solution by a temperature reduction technique. Their scintillation performance for fast neutron detection depended on the purity of the initial starting material. A light-yield-inhibitor-free starting material was specially synthesized and crystals from this material were compared to those grown from commercially available powders of trans-stilbene. The use of pure material made possible the growth of the large size crystals (>400 g) with excellent neutron-gamma discrimination performance, which are needed for use as a radiation detection material.
