Nazarov cyclizations abnormal

The abnormal Nazarov cyclization reported by Hiyama leads to transposed cyclopentenones by incorporating carboxylic acids as nucleophiles in the reaction medium. Both acyclic and monocyclic divinyl ketones can be employed, as shown in Scheme 15. Dioxolane acetals have also been used successfully in place of the carbonyl group.
