A novel and fully chemo- and stereoselective three component strategy leading to Z-α-chloroacrylates by a Pd0-catalyzed reaction of CO (1 atm) with 1,1-dichloro-1-alkenes and various alcohols is disclosed. This catalytic approach compares favourably with the Wittig type strategies as α-chloroacrylates of pure Z configuration are obtained in high yield.
本研究揭示了一种新型、完全化学和立体选择性的三组分策略,通过 Pd0 催化 CO (1 atm) 与 1,1-dichloro-1-alkenes 和各种醇的反应生成 Z-δ-氯丙烯酸酯。这种催化方法与 Wittig 类型的策略相比更有优势,因为它能以高产率获得纯 Z 构型的 α 氯丙烯酸酯。
