It is shown that benzocyclobutenols are excellent starting materials for the obtention of polycyclic aromatic ketones. Thus under basic conditions they lead to benzocyclenedione mono ketals which may be hydrolyzed into the corresponding benzocyclenediones. Under acidic conditions, a transposition takes place leading to indanone derivatives. The mechanism of this transposition is discussed.
结果表明,苯并环丁烯醇是获得多环芳族酮的极佳原料。因此,在碱性条件下,它们导致苯并环二酮单缩酮可被水解成相应的苯并环二酮。在酸性条件下,发生转座,生成茚满酮衍生物。讨论了这种转座的机制。
