A set of rhenium-catalyzed arylation-acyl cyclizations between (hetero)arylmagnesium halides and enol lactones through a cascade C(sp2)-C(sp2)/C(sp2)-C(sp2) bond formation under mild reaction conditions was developed. Indeed, a wide range of functional groups on both organomagnesium halides and enol lactones was well tolerated by the simple rhenium catalysis, thus furnishing polyfunctionalized indenones in one-pot fashion and with complete control of the regioselectivity. Moreover, this approach also provided a straightforward synthetic route to neolignan and (iso)pauciflorol F. Mechanistic studies demonstrated that the reaction involved a sequence of syn-carborhenation and intramol. nucleophilic addition
