phenylthioacetylene or ethoxyethyne. Acyl-substituted azulenones with a methoxy group in the cycloheptatriene moiety could be rearranged to spiro[4.5] compounds. Spiro[4.5] and bicyclo[5.3.0]decane ring systems were constructed en route to a formal synthesis of (±)-acorenol and synthesis of the hydroazulene core of pseudolaric acid, respectively.
通过2-芳基-2-氯酰基乙烯酮与苯硫基乙炔或乙氧基乙炔的反应,合成了具有角酰基取代基的Azulenones。在环庚三烯部分带有甲氧基的酰基取代的氮烯酮可以重新排列成螺[4.5]化合物。在分别正式合成(±)-阿拉伯烯醇和合成假丙酸的水az烯核心的途中,构建了螺[4.5]和双环[5.3.0]癸烷环系统。
