Abstract

A concise synthesis of novel substituted quinone derivatives from commercially available starting materials was developed. For this synthesis, classical photo-induced 6π-electrocyclization was utilized, followed by oxidative aromatization reaction, and subsequent oxidative coupling reactions in the presence of CuCl(OH)-TMEDA. The unique quinone derivatives were characterized by IR, 1H, and 13C NMR spectroscopies, and mass spectroscopic data analysis. In some cases, the keto dimers were obtained as significant intermediates for the quinone synthesis.
