Abstract
AbstractFerric chloride mediated dearomative spirocyclization of biaryl ynones for the synthesis of new series of densely functionalized 3,3‐spiroindanone derivatives has been reported. This study is the first to describe the regioselective synthesis of a five‐membered ring from biaryl ynones. The scope of the reaction is broad and the spirocyclic products were obtained in moderate to good yields (up to 87 %) and with high stereoselectivities.
