Abstract
The authors report a highly stereoselective one-pot synthesis of trans-2,3-disubstituted indanone derivatives from phenylalkynes with aldehydes in one pot. Although one-pot approaches for the synthesis of indanones via Nazarov cyclization of phenyl alkenyl ketone intermediates with stoichiometric amounts of promoters have been known as convenient methods, the authors develop the first catalytic one-pot approaches to the formation of indanones by a reaction of alkyne and aldehyde.
