Enticing structures: The formal syntheses of 1 and 2 were accomplished by using a cascade strategy involving an enyne cycloisomerization reaction and an intramolecular Diels–Alder reaction starting from 3. The resulting 4 underwent a late‐stage ring contraction to enable the preparation of a reported advanced intermediate, thereby constituting a formal synthesis of the structurally intriguing title
包埋结构:1和2的形式合成是通过级联策略完成的,该策略涉及烯炔环异构化反应和从3开始的分子内Diels-Alder反应。所得的4个化合物经历了后期的环收缩,从而能够制备已报道的高级中间体,从而构成了结构有趣的标题化合物的正式合成。
