Highly diastereoselective synthesis of cyclopentenones via a one-pot gold catalysis, Nazarov cyclization and alkylation cascade

Starting from readily available propargylic carboxylates, three sequential transformations [gold-catalyzed tandem reaction, scandium(III) trifluoromethanesulfonate catalyzed Nazarov cyclization, alkylation reaction] in a one-pot process led to the formation of cyclopentenone derivatives in excellent diastereoselectivities and moderate to good overall yields.
