Additions of organodilithium reagents to dialdehydes allow for construction of [1.1.1.1]metacyclophane macrocycle in similar to 40% yield in the ring forming step, without resort to standard high dilution techniques. The present methodology is complementary to the conventional condensations leading to phenol- and resorcinol-based cyclotetramers.
