A 3,4,5-trimethylphenol and Lewis acid dual-catalyzed cascade reaction of donor-acceptor (D-A) cyclopropanes via ring-opening and cyclization is developed. In this reaction, a phenolic compound was used as a covalent catalyst for the first time. Additiona

A synthetic route to 7-acetoxybenzanthracenes is described based on the generation of 1-benzylisobenzofurans and their capture with methyl acrylate in a Diels-Alder reaction.The 1,4-epoxy-1,2,3,4-tetrahydronaphthalene derivatives so formed are aromatized to naphthoate esters under acidic conditions and hydrolyzed to the naphthoic acids, and these are cyclized to the 7-acetoxybenzanthracenes with zinc chloride in acetic anhydride.

The known equilibrium between the tautomers benzalphthalan (1) and 1-benzylisobenzofuran (2) has been exploited as a synthetic route to novel substituted polycyclic aromatic compounds.The isobenzofuran was captured in a series of Diels-Alder reactions to
