Waihangahia he putanga matatini ake o tenei rerenga Claisen rearrangement'' ka puta ma te whakawera i nga waipiro allylic i te aroaro o'' N, N -'' dimethylacetamide dimethyl acetal ki te hanga γ, δ - amide unsaturated.
Ko te tikanga, ko te putanga matatini ake o te rerenga korero ko te "Claisen rearrangement '' ka ahu mai i te waipiro allylic ki te γ, δ - amide unsaturated, a i whakawhanakehia e Albert Eschenmoser i te 1964. "
