To date, the general and catalytic α-arylation of cyclic 1,3-dicarbonyls remains elusive. We now report first Rh-catalyzed with benzocyclobutenols through a iodonium ylide strategy. Our strategy represents good solution for previously challenging sterically demanding aryl partners, which is especially appropriate structurally unique heteroaromatic 1,3-dicarbonyls. approach features mild conditions, readily available starting materials, high yields, excellent functional group-tolerance, simple operation, providing expedient access toward medically important 2-aryl (hetero)cyclic The practicality this demonstrated by gram-scale synthesis, one-pot numerous downstream transformations.
