, p. 53 - 69 (2015/10/19)
The synthesis, structure, and conformational behaviour of three imidazolium cyclophanes that incorporate one or two 4-tert-butylphenol or 4-tert-butylanisole groups as meta-disubstituted linkers in the macrocycle is described. The cyclophanes containing a

Various syn- and anti-9-substituted [3.3]metacyclophane-2,11-diones are obtained by the coupling reaction of the corresponding 2,6-bis(bromomethyl)benzenes (3) with 2,6-bis[2-cyano-2-(toluenesulfony)ethyl]-4-tert-butyl-1-substituted benzenes (4) in dimeth

Only a few oxygenated homologues of calixarenes have been reported to date, although a large number of structures can be envisaged. These can give rise to a practically new and interesting class of cyclophanes and deserve a systematic investigation. The s
Synthesis of dibenzopyrenes and pyrenes via photolytic sulfur extrusion and intramolecular cross-coupling reactions of dithia[3.3] (1,3)naphthalenophanes and dithia[3.3]metacyclophanes

, p. 6476 - 6484 (2007/10/03)
The syntheses of several substituted dithia[3.3]metacyclophanes and dithia[3.3](1,3)naphthalenophanes are reported and their photolyses in triethyl or trimethyl phosphite are described. Under these conditions, the corresponding tetrahydrodibenzopyrenes and tetrahydropyrenes are produced in a one-pot procedure when the precursor dithianaphthalenophanes and dithiacyclophanes possess at least one intraannular methoxyl group. A mechanism with supporting evidence is proposed to account for these results. Structural determinations of the four isomeric 11,22-dimethoxy-2,13- dithia[3.3](1,3)naphthalenophanes by NMR and X-ray single-crystal diffraction studies are also described. The syntheses of the novel anti-transoid- and anti-cisoid-[2.2](1,3)naphthalenophanes are also described.

Tri-tert-butyltrihydroxymetacyclophane 13 was prepared in 6 steps from p-tert-butylanisole in 25percent overall yield by using the TosMIC method, followed by Wolff-Kishner reduction and demethylation with boron tribromide.AlCl3/MeNO2-catalyzed tran
