  Regioselective synthesis and photooxygenations of furonaphthopyrones starting from 2,7-naphthalenediol

  摘要：

  Three angular furonaphthopyrones 4, 9, 12 were regioselectively synthesized starting from 2,7-naphthalenediol in three steps, respectively. An easy separation of Pechmann condensation products 1 and 2 of 2,7-naphthalenediol with ethyl acetoacetate was described. The photooxygenations of 4, 12 were investigated and a hydroperoxide 18 was isolated and fully characterized. (C) 1997 Elsevier Science Ltd.
