Angle‐strained alkyne‐containing π‐conjugated macrocycles are attractive compounds both
in functional materials chemistry and biochemistry. Their interesting reactivity as well as …

The development of large π-conjugated polycyclic heteroaromatic materials is of immense
interest, both in the academic as well as the industrial community. Herein, we present the …

Abstract Two new 6, 17‐di‐tert‐butyl‐[3] metacyclo [3](1, 3)‐pyrenophane‐2, 11‐diones 8 a–
b were synthesized by the coupling reaction of 1, 3‐bis (bromomethyl)‐7‐tert‐butylpyrene 5 …

The synthesis of the strained trimethyled anti-[2.2] metacyclophanes 5a and 5b is reported.
They were synthesized by ring contraction of the corresponding unstrained cyclic precursors …

Abstract Methyl substituted 8‐methoxy [2.2] MPCPs 8 a–b were obtained via the
corresponding thiacylophanes and its oxidized products. Lewis acid‐catalyzed (AlCl3 …

A series of syn-and anti-[2. n] metacyclophan-1-enes have been prepared in good yields by
McMurry cyclizations of 1, n-bis (5-tert-butyl-3-formyl-2-methoxyphenyl) alkanes …

Abstract [3.1. 1] Metacyclophane ([3.1. 1] MCP) 6 a containing two benzofuran rings was
obtained by treatment of [3.3. 3] MCP‐dione 5 with trimethylsilyl iodide. The precursor 5 was …

Abstract Anti‐8‐methoxy [2.2] metacyclophanes (MCPs) 5 a–b were obtained via pyrolysis of
the corresponding syn‐thiatetraoxide cyclophanes 4 a–b. Coupling reactions of 4‐tert‐butyl …

The reductive coupling reaction of 1, 4-bis (3-acetyl-5-tert-butyl-2-methoxyphenyl) butane 3
was carried out using TiCl 4-Zn in pyridine followed by a McMurry coupling reaction to afford …

The syntheses of syn‐[2. n] metacyclophan‐1‐enes (n= 5, 6, 8) in good yields using the
McMurry cyclization of 1, n‐bis (3‐formyl‐4‐methoxyphenyl) alkanes are reported …
