Favorskii Rearrangement

The video tutorial explores the Favorsky rearrangement, a classical reaction inducing ring contraction, invented by Alexi Favorsky in 1894. It details the mechanism involving enolate formation, nucleophilic attack, and the formation of a cyclopropanone intermediate. The tutorial also discusses the reaction's application to isomeric alpha halo ketones and the confirmation of symmetrical intermediates. The Favorsky rearrangement is highlighted for its utility in synthesizing complex structures, such as Eaton's cubine and the alkaloid epibatidine, showcasing its importance in organic synthesis.
