  Reactions of Diphenyl(phenylethynyl)selenonium Salts with Active Methylene Compounds and Amides:  First Isolation of Oxyselenuranes [10-Se-4(C3O)] as a Reaction Intermediate

  摘要：

  The reaction of the diphenyl(phenylethynyl)selenonium triflate 1a with active methylene compounds 5 and t-BuOK in THF gave furan derivatives 6. The [10-Se-4(C3O)] selenuranes 8a and 8b could be isolated from the reactions with benzoylacetonitrile 5f and with 1,3-indandione 5g, respectively, as reaction intermediates. The structures of the selenuranes 8 were elucidated by X-ray crystallography and Se-77 high-resolution solid-state NMR spectroscopy. The selenuranes 8 underwent ligand coupling on standing at room temperature or refluxing in chloroform and gave the furan derivatives 6 and the ring-opened product 9. Similarly, the reaction of 1a with benzamide 13a and pivalamide 13d in the presence of NaH in THF afforded oxazole derivatives 14.

  regioselective synthesis of 2,3,4-trisubstituted furans using AgNO3 catalyst from haloalkynes in a one-pot procedure has been reported. The transformation consists of a sequential silver-catalyzed nucleophilic addition and cyclization reaction of haloalkynes. A wide variety of haloalkynes can be used in this chemical process.
