MeOTf-catalyzed annulation of aldehydes and arylalkynes leading to 2,3-disubstituted indanones†
Abstract
The MeOTf-catalyzed construction of indanones via arylalkyne–aldehyde metathesis and subsequent Nazarov cyclization has been reported. This reaction represents a sustainable and atom-economical approach for the preparation of indanones from readily available substrates with high stereoselectivity.
