    Notes: Thermische Cyclisierungen von Dienen, Eninen, Enonen und ähnlichen ungesättigten Systemen illustrieren das präparative Potential der intramolekularen En-Reaktion. Eine Fülle substituierter, anellierter und überbrückter Ringsysteme, darunter auch Naturstoffe, sind so auf regio- und stereoselektive Weise zugänglich. Zahlreiche Beispiele dienen dazu, die Möglichkeiten, Grenzen und gemeinsamen Gesetzmäßigkeiten dieser Cyclisierungs- und der dazu inversen Ringöffnungs-Reaktion zu umreißen. Manche dieser Cyclisierungen sind in industrieller Größenordnung durchführbar.

    Notes: Thermal cyclizations of appropriate dienes, enynes and related unsaturated systems, some of them carried out on an industrial scale, demonstrate increasingly the preparative power of the intramolecular ene reaction. A variety of substituted, fused and bridged ring systems, including natural products, are thus easily accessible in a regio- and stereo-selective manner. Numerous examples are discussed systematically illustrating the possibilities, limitations, and common features of this cyclization reaction and its reverse ring-opening process.
