The thermal conrotatory ring closure of divinyl ketones in acidic medium leads to cyclopentenones with excellent yields. This reaction represents one of the best methods for cyclopentenone annelation. The synthesis of the divinyl ketone precursors and cyclisation conditions are summarised in this review. 1.
