A new strategy for the synthesis of alpha-hydroxy ketones by samarium(II) iodide-mediated three-component coupling of organic halides, an isocyanide, and carbonyl compounds is disclosed.An (alpha-iminoalkyl)samarium(III) species is generated in situ by treatment of an organic halide with 2 equiv of samarium(II) iodide in the presence of 2,6-xylyl isocyanide.Subsequent treatment of the mixture with a carbonyl compound affords alpha-hydroxy imines, which are converted by acid-catalyzed hydrolysis to the corresponding alpha-hydroxy ketones.The mild reaction conditions employed are compatible with a variety of functionalities including terminal acetylenes and trimethylsilyl ethers.Application of the method to the synthesis of alpha-hydroxy aldehydes is also presented.

Ligands have been synthesized containing two vicinal dioxime functions joined by a carbon chain to which is attached in the centre a bromomethyl or chloromethyl group (20, 22, 25).These ligands, upon reaction with cobalt(II) chloride in the presence of pyridine and sodium borohydride afforded bridged intramolecularly alkylated cobaloximes.When the vicinal dioxime functions are separated by a chain of nine carbon atoms mainly dimeric complexes are formed.Two of these, 26 and 27, were isolated and characterized by spectroscopic methods and their structures were established by X-ray crystallography.Ligands containing eleven or thirteen carbon atoms between the dioxime functions afforded mainly monomeric cobaloximes with cis configuration, e. g. 28.The trans-monomeric complex 30 was produced along with the cis isomer when the number of carbon atoms in the bridge was raised to fifteen.

Silica bromide as heterogeneous reagent is prepared from the reaction of silica gel with PBr3 as a nonhydroscopic, filterable, cheap, and stable yellowish powder that can be stored for months. The results show that the silica bromide is a suitable and efficient reagent for conversion of alcohols to alkyl bromides under mild conditions at room temperature. The easy availability of this reagent makes this simple procedure attractive and a practical alternative to the existing methods.

O-Protected cyanohydrins were found to serve as a source of the nitrile within the intramolecular cobalt-mediated [2+2+2] cycloaddition to pyridines. Several 6-substituted 1,2,3,4,7,8,9,10-octahydrophenanthridines were synthesized using this cycloaddition of diyne-cyanohydrins. By introduction a TMS group a divergent way to such phenanthridine derivatives was elaborated. Georg Thieme Verlag Stuttgart – New York.

Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction.

Coupling reactions of lithium compounds, (Z)-carbonyl olefination of phosphonium ylides and ‘crossed’ Wittig olefination of bisylides are the key reaction steps in the synthesis principle for nonconjugated, bisolefinic Lepidoptera pheromones and structural analogs. Double unsaturated (E,Z)- and (E,E)-1-vinyl halides are converted into the corresponding (E,Z)- and (E,E)-1-vinyl lithium compounds and coupled selectively to (E,Z)- and (E,E)-alkadienols, alkadienals and alkadienyl acetates with different carbon chain length, geometry and relative positions of double bonds. ‘Crossed’ Wittig reactions of 1,omega-alkylidene bisylides with two different alkanals gives rise to the formation of corresponding (Z,Z)-dienic sex attractants and derivatives. A monounsaturated (E)-1-vinyl iodide is the synthon for the preparation of an (E)-alkenyl bromide which is converted to an (E)-alkenyl phosphonium salt and (Z)-selectively olefinated to (Z,E)-isomers of moth sex pheromones.

Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran, molecular formula is C9H17BrO2.

Osteomyelitis is a difficult to treat bacterial infection of the bone. Delivering antibacterial agents to the bone may overcome the difficulties in treating this illness by effectively concentrating the antibiotic at the site of infection and by limiting the toxicity that may result from systemic exposure to the large doses conventionally used. Using bisphosphonates as osteophilic functional groups, different forms of fluoroquinolone esters were synthesized and evaluated for their ability to bind bone and to release the parent antibacterial agent. Bisphosphonated glycolamide fluoroquinolone esters were found to present a profile consistent with effective and rapid bone binding and efficient release of the active drug moiety. They were assessed for their ability to prevent bone infection in vivo and were found to be effective when the free fluoroquinolones were not.
