标题:Synthesis Of .Beta.-Resorcylic Macrolides Via Organopalladium Chemistry. Application To The Total Synthesis Of (S)-Zearalenone
摘要:The Beta-Resorcylic Macrolides Are A Class Of Naturally occurring 12-And 14-Membered Macrolides. Zearalenone (1),A 14-Membered Macrolide Of This Type,Displays Useful Biological Activity,Which Has Led To Great Synthetic Interest. In This Paper The Intramolecular Coupling Reaction Of An Organostannane With An Electrophile Is Used To Construct Beta-Resorcylic Macrolides. The Intramolecular Coupling Of An Aryl Iodide With A Vinylstannane Provided The Highest Yield Of Lactones. This Methodology Was Then Used To Prepare (S)-Zearalenone (1).

标 题:Synthesis of functionalized macrocycles by ring closing metathesis
发明人：FUERSTNER ALOIS; LANGEMANN KLAUS; KINDLER NICOLE
权利人:STUDIENGESELLSCHAFT KOHLE MBH
摘要:The invention concerns an improved process for the preparation of macrocyclic products with 12 or more ring atoms containing one or more polar functional groups on the ring and/or one or more heteroatoms within the ring by ring closing metathesis (RCM) of suitably substituted diene precursors even if the substrates are devoid of any kind of conformational preorganization. Metal carbene complexes of Ru, Mo, W, Re, Os, which are tolerant towards the respective functional group and can either be isolated or prepared in situ are used as catalysts or catalyst precursors. Preferred catalysts or catalyst precursors are ruthenium complexes of the general type XX1LL1Ru=CRR1, wherein X, X1=halogen, L, L1=trialkylphosphine, R, R1=H, Ph, CH=CPh2 denote the most preferred embodiment. The process can be applied to the synthesis of olfactory compounds, perfumary ingredients, pheromones, crown ethers, antibiotics and pharmaceuticals for human and veterinary medicine.

摘要:A highly sensitive technology enabling selective recognition of aflatoxins such as in contaminated cereal samples. Methods for the synthesis of AgNP-containing MIP membranes from the monomer mixtures containing both methacrylate monomers and oligomers as well as AgNOs solution in dimethylformamide enable the detection system. The AgNP were formed in the structure of the polymeric membranes during the pre-heating step followed by the UV-initiated polymerization. The highly selective sensor elements where MIP membranes are combined with the Ag nanostructures as signal amplifiers (LSPR-MIP nanochips) can be stored separately and used with a simple optical recognition system as selective elements of point-of-care sensor devices, even in in-field conditions. Composite plasmonic membranes provide both highly selective recognition of the target toxin and the generation of an enhanced optical signal, allowing aflatoxin B1 detection at ultralow concentrations.
