promoting sp2 C-H bond insertion at the para position of unprotected phenols because of the exceptionally chemical reactivity of gold-stabilized carbophilic carbocations. Herein, we present a gold(i)-catalysed three-component reaction between phenols, diazocarbonyl compounds and allenamides, affording the corresponding three-component reaction products with excellent geometric selectivity (E : Z > 20 : 1)
