    Description / Table of Contents: Stereospecific Synthesis of cis-/trans-Substituted 1-Alkenylcyclopentanes and -cyclopentenesSynthesis of cis-/trans-substituted 1-alkenylcyclopentanes (11/11a, 12/12a, 13/13a) and -cyclopentenes (17/17a) via stereospecific ring-opening of 2,2-dibromocyclobutanones (7, 5) is described. The geminal dibromide as a functional group in the compounds 8/8a, 6/6a allows selective reactions, which can be used for the aimed synthesis of 1,2-disubstituted five-membered ring systems.
    Notes: Eine Synthese von cis-/trans-substituierten 1-Alkenylcyclopentanen (11/11a, 12/12a, 13/13a) und-cyclopentenen (17/17a) durch stereospezifische Ringöffnung von 2,2-Dibromcyclobutanonen (7, 5) wird beschrieben. Das geminale Dibromid als funktionelle Gruppe in 8/8a, 6/6a gestattet selektive Reaktionen, die zum gezielten Aufbau von 1,2-disubstituierten Fünfringsystemen präparativ genutzt werden können.

    Description / Table of Contents: Stereichmistry of Fucoserratene, the Gamete Attractant of the Brown Alga Fucus serratys L.Fucoserratene, the female sex attractant (gynogamone) from the ova of the seaweed Fucus serratus L. is 1,3-trans,5-cis-octatriene, as proven by comparison with the synthesized stereo-isomer. The systematic synthesis of all four cis, trans isomers of 1,3,5-octatriene and their physical properties are described.
    Notes: Fucoserraten (C8H12), der Gametenlockstoff (Gynogamon) der Eier des Seetangs Fucus serratus L. ist 1,3-trans,5-cis-Octatrien, wie durch Vergleich mit den synthetisierten Stereo-meren bewiesen wird. Die systematische Synthese aller vier cis, trans-isomeren 1,3,5-Octatriene und ihre Eigenschaften werden beschrieben.

    Description / Table of Contents: Synthesis of Multifiden, the Gamete-Attractant of the Phaeophyte Cutleria multifida and Some of its Isomers. A Contribution to the Cope Rearrangement of 1-AlkenylcyclopentenesSynthesis of multifiden (1) and of two of its structural isomers 16 and 17 is described. Regioselective addition of dihalogenoketenes to dimeric cyclopentadiene 3 to yield 4a/b or 5a/b gives easy access to the pheromone system.
