The practical synthesis procedure of substituted tetraphenylene derivatives involving the synthesis of a precursor for 4, 7-dunethoxyisobenzofuran and Diets-Alder addition of 4, 7-dimethoxyisobenzofuran generated in situ to 5, 6, 11,12-te-tradehydrodibenzo[a,e]cyclooctene, followed by a low valent titanium mediated deoxygenation to give 1,4, 11, 14-tetra-methoxy-dibenzo[b, n] tetraphenylene, which can be further demethyiated to the corresponding phenolic compound, which was acetylated to afford 1,4,11,14-tetraacetoxy-dibenzo-[ b, n] tetraphenylene.
