    Siyang Xing Dr.
    Brückenbau: Eine Lewis-Säure-vermittelte intramolekulare [3+2]-Cycloaddition zwischen Cyclopropan-1,1-diestern und Aldehyden, Ketonen oder Iminen (siehe Schema) eröffnet einen allgemeinen und effizienten Zugang zu verbrückten Oxa- und Aza[n.2.1]-Gerüsten (n=2,4). Als Anwendungsbeispiel wurde die Kernstruktur von Platensimycin aufgebaut. [source]

    Spannung im Ring: Zwei neue Cyclopropanierungsreaktionen (siehe Schema; LA=Lewis-Säure, Nu=Nucleophil) verlaufen mit hoher Stereoselektivität unter erstaunlich milden Bedingungen. In der ersten sind Epoxide die Methylenquelle in der Synthese enantiomerenangereicherter Cyclopropane. In der zweiten wird der Anwendungsbereich der etablierten allylischen Alkylierungen hin zur Synthese dreigliedriger Ringe in exzellenter Enantioselektivität erweitert. [source]

    Synthesis of Cyclopropanes via Organoiron Methodology: Stereoselective Preparation of Bi(cyclopropyl)s

    EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 23 2007
    Rajesh K. Pandey
    Abstract Cyclopropanation of [2-(alkenyl)pentenediyl]Fe(CO)3 complexes (4) proceeds in a diastereoselective fashion to afford [2-(cyclopropyl)pentenediyl]Fe(CO)3. The relative stereochemistry of the products was established by X-ray crystallography. The diastereoselectivity is rationalized on approach of the cyclopropanation reagent on the sterically more exposed face of 4. Oxidatively induced reductive elimination afforded stereodefined bi(cyclopropyl)s. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007) [source]
