Polycyclic oxygenated compounds have been generated from penta- or hexadienyl propargyl ethers by a new procedure that combines the selective formation of a 1,3-diene by ring-closing metathesis (RCM), a Diels–Alder (DA) reaction and subsequent cross-metathesis (CM) with a chosen alkene, which allows the functionalization of the vinyl group generated during the first step. All these processes can be
多环含氧化合物已通过一种新方法由五-或己二烯基炔丙基醚生成,该方法结合了通过闭环复分解 (RCM)、Diels-Alder (DA) 反应和随后的交叉反应选择性形成 1,3-二烯。与选定的烯烃复分解(CM),这允许在第一步中产生的乙烯基官能化。所有这些过程都可以在一锅反应中进行,产率高达 63%。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
