Abstract:
A one-pot cascade process of benzyl enoldiazoacatates, initiated by dirhodium(II)-catalyzed intramolecular cyclopropene formation, occurs via a subsequent Buchner reaction and Cope rearrangement to provide straightforward access to bicyclo[3.2.2]nonatriene derivatives in high yields and selectivities.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
