report a two-step preparation protocol of α-benzoyloxyalkylzinc bromides from α-benzoyloxyalkyl selenides, and their application to palladium-catalyzed cross-coupling reactions with aryl and vinyl iodides. The developed method effectively provides a variety of benzoyl-protected benzylic and allylic alcohol derivatives through the formation of C(sp3)–C(sp2) bonds without affecting various polar functional
在这里,我们报告了由α-苯甲酰氧基烷基硒化物制备α-苯甲酰氧基烷基锌溴化物的两步方法,及其在钯催化的芳基和乙烯基碘的交叉偶联反应中的应用。所开发的方法通过形成C(sp 3)–C(sp 2)键有效地提供了多种苯甲酰基保护的苄基和烯丙基醇衍生物,而不会影响各种极性官能团。
