Described herein is a Pd-catalyzed haloallylation of aromatic ynol ethers and allyl chlorides, allowing facile access to (1E)-α-chloroenol ethers in a highly regio- and stereoselective manner. The synthetic utility of this method is demonstrated well by the synthesis of the stereodefined multisubstituted enol ethers and α-allylated carbonyl compounds.
本文描述了一种钯催化的芳香丙炔醚和氯丙烯的卤烯烃化反应,能够以高的区位选择性和立体选择性方便地制备(1E)-α-氯烯醇醚。该方法的合成实用性通过合成立体定义的多取代烯醇醚和α-烯丙基碳基化合物得到充分证明。
