The mode of the thermal cyclization of enyne-allenes 1 depends on ring strain effects: when the ene functionality is part of a benzene, cyclohexene or cycloheptene ring the novel C2-C6biradicrd cyclization is observed, while when it is part of a cyclopentene ring the Myers-Saito cycloaromatization i
