The Carroll reaction is a version of this reaction that is followed by a decarboxylation step, and the shikimate pathway creates prephanate in a version of this reaction catalyzed by chorismate mutase. Trichloroacetamides can be created in a heteroatom version of it named for Overmann, while combining it with a Staudinger ligation gives the Chen-Mapp reaction. Performing it on an allylic alcohol or allylic acetate gives the Johnson and Ireland modifications respectively, while unsaturated amides are created in the Eschenmoser modification. The Cope rearrangement shares its [3,3]-sigmatropic mechanism. For 10 points, name this reaction which c
