Regioselective Decarboxylative Aromatization of Benzonorcaradienes to Substituted 1‐Acylmethyl‐4‐Arylnaphthalenes

Abstract

Tf2NH‐mediated decarboxylative dearomatization reaction of benzonorcaradiene γ‐ketoacids, in situ generated by intramolecular alkenylation of alkynylcyclopropane γ‐ketoacids or their tert‐butyl esters, has been described for regioselective synthesis of polyfunctionalized 1‐acylmethyl‐4‐arylnaphthalenes.
