Olefin‐Bildung durch eliminierende Dimerisierung und eliminierende Kreuzkupplung von Carbenoiden: eine stereochemische Herausforderung

Abstract: Bei der Dimerisierung von Carbenoiden entstehen Olefine, und zwar über die Bildung eines At‐Komplexes, eine nachfolgende 1,2‐Metallat‐Umlagerung und eine abschließende β‐Eliminierung. Da jeder dieser Schritte stereospezifisch ist, kann man das stereochemische Endergebnis nachvollziehen und – im Prinzip – auch steuern, vorausgesetzt, die absolute Konfiguration der reagierenden Carbenoide ist festgelegt. Eine eliminierende Kreuzkupplung zweier unterschiedlicher Carbenoide ermöglicht eine Aufbaureaktion, bei der … Show more

“…While this side reaction does not allow for choosing the desired configuration at the elimination stage anymore, both 50 g ‐ E and 50 g ‐ Z were obtained by appropriate like or unlike combination of starting materials. In the meantime, this method has been applied by Blakemore and co‐workers to the synthesis of a p‐glycoprotein inhibitor and its isomere [53] . The overall concept of coupling carbenoids in order to make alkenes was discussed by Hoffmann and Blakemore in an interesting review article [53] …”
