Transannular cyclization of dehydrobenzoannulenes is a powerful method to construct new carbon frameworks that are otherwise difficult to achieve. In their Communication on page 4184 ff. , Y. Tobe and co‐workers show that the reaction of dehydrobenzo[14]annulenes with n ‐butyllithium leads to an unprecedented oxidative cyclodimerization to form eight‐membered‐ring products, following threefold transannular bond formations across a 14‐membered ring.
