Synthesis of Functionalized Allylsilicone Compounds via Rhodium-Catalyzed Conjugate Addition of (E)- or (Z)-[3-Trimethylsilyl-1-propenyl]boronic Acids to Enones
The rhodium-catalyzed conjugate addition of (E)-Me 3 SiCH 2 CH=CHB(iPrO) 2 or (Z)-Me 3 SiCH 2 (C 4 H 9 )C=CHB(iPrO) 2 to enones provided a novel method for the synthesis of allylsilicone compounds possessing a carbonyl group inthe same molecule, which are versatile intermediates for intramolecular allylsilylation, giving cyclobutanols on treatment with Bu 4 NF.
(E)-Me 3 SiCH 2 CH=CHB(iPrO) 2 或(Z)-Me 3 SiCH 2 (C 4 H 9 )C=CHB(iPrO) 2 与烯酮的铑催化共轭加成提供了一种新方法用于合成在同一分子中具有羰基的烯丙基硅氧烷化合物,这些化合物是分子内烯丙基甲硅烷基化的通用中间体,用 Bu 4 NF 处理得到环丁醇。
