vacuum pyrolysis of the 1a,1b,6b,6c-tetrahydro-oxireno[2′,3′:3,4]cyclobuta[1,2-b][1]benzofurans (5), prepared from the benzoxepines (3)via two steps, results in ring-opening to give the novel 1,4-benzodioxocines (6), whose spectral data indicate that they are non-aromatic.
闪蒸真空热解由苯并恶庚烷(3)制备的1a,1b,6b,6c-四氢-氧杂壬酸[2',3':3,4]环丁[1,2- b ] [1]苯并呋喃(5)通过两个步骤,导致开环,得到新颖的1,4-苯并二氧杂环酮(6),其光谱数据表明它们是非芳香族的。
