A (4+1)-cycloaddition is reported between 1,2-dicarbonyls and aza-o-quinone methide precursors to access 2,3-dihydroindoles bearing a tetra-substituted carbon center. The utilization of dioxyphospholenes as carbene surrogates provided dihydroindoles in 20–90 % yield, wherein the electronic nature of the dioxyphospholene impacts its role in the reaction.
