The Nazarov cyclization of β-carbonyl-β′-furyl-divinyl ketones and related compounds as induced by perchloric acid

Diluted solutions of perchloric acid and acetic anhydride are introduced as a new catalyst for cationic cyclizations. The influence of the strong acid concentration and the nature of the anhydride have been studied in four types of Nazarov substrates. Diluted solutions of perchloric acid and acetic...
