Abstract

The first catalytic method for the cyclization of vinyl-cyclopropyl ketones (formal homo- Nazarov reaction) is reported. Starting from activated cyclopropanes, heterocyclic, and carbocyclic compounds were obtained under mild conditions using Brønsted acid catalysts. Preliminary investigation of the reaction mechanism indicated a stepwise process.
