developed syntheses for benzo[cd]azulenes. By using very common catalysts and reagents, such as t-BuOK, HCl, and mCPBA, the commercially available guaiazulene is converted in three steps into tricyclic tropone derivatives. Electrophilic aromatic substitution reactions of guaiazulene proceed without a catalyst. Complex one-pot reactions convert 1′-hydroxyalkyl azulenes into tricyclic heptafulvenes, and
由于我们对蛋白激酶调节化合物的兴趣,我们开发了苯并[ cd ] azulenes的合成方法。通过使用非常常见的催化剂和试剂,例如t- BuOK,HCl和m CPBA,可将市售的愈创木酚分三步转化为三环tropone衍生物。愈创木烯的亲电子芳族取代反应在没有催化剂的情况下进行。复杂的单罐反应,转换1'-羟薁成三环heptafulvenes,最后,所述温和的氧化剂米CPBA裂解semicyclic C = C双键,得到tropones。
