Abstract
A new gold(I) self-relay catalysis consisting of a 3,3-rearrangement, Nazarov cyclization and Michael addition cascade of 1,3-enyne acetates with aurones and their derived azadienes is reported, and used to produce a series of densely functionalized cyclopentenones bearing a cyclic quaternary stereocenter in moderate to good yields under mild conditions. This tandem protocol demonstrates high regioselectivity, broad substrate flexibility and good functional group tolerance of substrates without inert atmosphere protection, providing a catalytic and convergent approach for creating all-carbon stereoscopic centers.
