method of silyl dienol ethers via 1,4-Brook rearrangement–Wittig reaction sequence has been developed. This tandem reaction proceeded via the intramolecular silyl migration step, which enabled stereoselective formation of phosphorane intermediates. The reaction is operationally simple and high yielding, thus providing a new useful formula for silyl dienol ether synthesis.
已开发出一种通过1,4-Brook重排-Wittig反应序列合成甲硅烷基二烯醇醚的新型一锅法。该串联反应通过分子内甲硅烷基迁移步骤进行,该步骤使得能够立体选择性地形成膦烷中间体。该反应操作简单且产率高,因此为甲硅烷基二烯醇醚的合成提供了新的有用的配方。
