    Synthesis of azirines containing aldehyde functionality and their utilization as synthetic tools for five membered oxazoles and isoxazoles

    JOURNAL OF HETEROCYCLIC CHEMISTRY, Issue 2 2008
    Sulagna Brahma
    A simple and useful procedure for the synthesis of azirines containing aldehyde functionality from open chain bromo/chloro-aldehydes at room temperature is reported. The scope of the ring expansion reaction of a number of 3-substituted-2-formyl-azirines has been examined using different oraganometallic catalysts and a variety of Lewis acids. [source]

    Application to the Synthesis of Fused Indoles.
    Abstract A copper-catalyzed photochemical cyclization/ring expansion reaction is developed for the preparation of a variety of fused indole derivatives. [source]


    Carbonyl group-containing organometallic intramolecular-coordination five-membered ring compounds

    APPLIED ORGANOMETALLIC CHEMISTRY, Issue 5 2010
    Iwao Omae
    Abstract Carbonyl group-containing organometallic intramolecular-coordination five-membered ring compounds are easily synthesized by the following five reaction methods: (1) cyclometalation, especially, orthometalation reactions; (2) the reactions of the moieties of an unsaturated carboncarbon bond attached to a carbonyl group (CCCO, CCCO); (3) the reactions of an unsaturated carboncarbon bond with carbon monoxide (CC and CO, CC and CO); (4) carbonylative ring expansion reactions; and (5) others. These compounds are very easily and regio-specifically synthesized with many kinds of metal compounds, including both transition metals and main group metals. Many of such the reactions are easily applied to organic syntheses. Copyright © 2010 John Wiley & Sons, Ltd. [source]
