“…Interestingly, the “dimerization” of a hexose substrate (entry 4) proceeds without double bond isomerization,36 although complete conversion cannot be reached after 24h of reflux. Surprisingly, the product is formed with remarkably high E / Z ‐selectivity (11:1) compared to the Grubbs catalyst 2a which commonly yields dimeric spacer‐linked hexoses in the E / Z ratio of 3 : 1 to 5 : 1 37. This excellent selectivity may be ascribed to the “bulkiness” of the solid phase.…”

“…Eine praktische Anwendung ist die Analyse des Z/E-Gemischs des verbrückten homodimeren Aminoglycosids 1 (Schema 1), das durch Metathese-Olefinierung erhalten wurde. [22,23] Im Protonen-Spektrum treten zwei eng benachbarte Signale mit einer relativen Intensität von etwa 70:30 auf. Anhand von Literaturdaten [1,24] [1] Das hier vorgestellte Experiment ermöglicht die einfache Bestimmung der Konfiguration an der Doppelbindung symmetrischer Moleküle.…”
