Designing Donor‐Acceptor Cyclopropane for the ThermalSynthesis of Carbocyclic Eight‐Membered Rings
Résumé
An access to functionalised eight-membered carbocyclic ring compounds was developed by simply stirring an unusual vinylogous Donor-Acceptor Cyclopropane (DAC) in boiling o-xylene. Both experimental and computational studies were performed to explain the diastereoselectivity/regioselectivity transfer observed and to provide an overall picture of the mechanism.
