of silyl-dienol ethers of unblocked cyclic enones with the utilization of palladium-catalyzed, modified Kuwajima–Urabe conditions. We have also successfully explored a new exo-ε-arylation of silyl-trienol ethers of π-extended cyclic enones. In addition, we also report, herein, exclusive γ- and ε-alkenylation of silyl-dienol and silyl-trienol ethers of cyclic enones.
我们在此报告了对未封闭的环状烯酮的甲硅烷基二烯醚的简单和区域选择性内-以及外-γ-芳基化的广泛研究,并利用了钯催化的改良的Kuwajima-Urabe条件。我们还成功地探索了π-延伸的环烯酮的甲硅烷基-三烯醇醚的新的外-ε-芳基化。另外,在此,我们还报道了环状烯酮的甲硅烷基-二烯醇和甲硅烷基-三烯醇醚的排他性γ-和ε-烯基化。
