An eight-step synthesis of (±)-grandisol features a key sequence involving a high-yielding, microwave-assisted enyne metathesis to yield a 1-alkenylcyclobutene that is semihydrogenated to yield a silyl-protected grandisol. Metathesis catalyst screens revealed an intriguing trend whereby substrate conversion correlated strongly with the identity of the ligands on the catalyst. In addition, new reactivity
(±)-grandisol 的八步合成具有一个关键序列,包括高产、微波辅助的烯炔复分解,以产生 1-烯基环丁烯,然后半氢化以产生甲硅烷基保护的 grandisol。复分解催化剂筛选揭示了一个有趣的趋势,即底物转化与催化剂上配体的特性密切相关。此外,还描述了 1-烯基环丁烯对氢化的新反应性。
