Knoevenagel adducts (cyclohexylidenemalononitriles) and two different propargyl electrophiles serve as carbon sources for assembling diverse 6/7/5 tricycloalkanes, a common terpenoid framework. The sequence involves three unique reactions: 1) deconjugative propargylation, 2) one‐pot enyne Cope rearrangement/deconjugative propargylation, and 3) an allenic Pauson–Khand reaction.
环己酮衍生的Knoevenagel加合物(环己叉基
丙二腈)和两种不同的炔丙基亲电试剂可作为碳源来组装各种6/7/5
三环烷烃(一种常见的萜烯骨架)。该序列涉及三个独特的反应:1)去共轭炔丙基化; 2)单罐烯炔应对反应重排/去共轭炔丙基化; 3)烯丙基Pauson-Khand反应。
