Synthesis and spectrokinetic studies of a new family of dimethyl [2H]-chromenes: dimethyl 6-aryl-2,2dimethyl-[2H]-chromene-7, 8-dicarboxylates

The synthesis of a series of dimethyl 6-aryl-2,2-dimethyl-[2H]-chromene-7,8-dicarboxylates is described. The photochromic properties of this new family of dimethyl-[2H]-chromenes have been studied in solution, under continuous irradiation. The presence of

A convenient synthesis of polysubstituted phenylphenols from substituted anilines

2' and 4'-Substituted arylfurans react with DMAD in the presence of Lewis acid to afford Diels-Alder adducts with good yields; a subsequent spontaneous or an acid-induced ?-elimination leads to polysubstituted phenylphenols.
