remained unchanged. This reaction was applied to a large variety of conjugated dienones, a trienone, and a tetraenone. Additionally, a tandem one-pot Wittig/conjugate-reduction reaction sequence was developed to produce γ,δ-unsaturated ketones directly from simple building blocks. In these reactions the byproduct of the Wittig reaction served as the catalyst for the reduction reaction. This strategy was
已经研究了使用三氯硅烷作为还原剂的三苯基氧化膦催化还原共轭多不饱和酮的范围。在所有研究的情况下,α,β-C=C 双键被选择性地还原为 C-C 单键,而所有其他可还原的官能团保持不变。该反应适用于多种共轭二烯酮、三烯酮和四烯酮。此外,还开发了串联一锅 Wittig/共轭还原反应序列,以直接从简单的构建单元生产 γ,δ-不饱和酮。在这些反应中,维蒂希反应的副产物作为还原反应的催化剂。然后将该策略用于合成天然存在的蛾信息素,以证明其在天然产物合成中的效用。
