Wagner-Meerwein Umlagerung

A

suprafaciale 1,2-Wanderung von Resten
die wohl konzertiert mit Ausbildung des carbokationischen Zentrums erfolgt.
Wandern können Ar-, Alk-, H- und Vinyl-Reste. Elektronenreiche Reste wandern
bevorzugt, und im Falle von chiralen Resten, erfolgt die Wanderung unter Retention.
