Regioselective synthetic methods were developed for 1,4- and 1,6-conjugate additions of Grignard reagent-derived organozinc(II)ates to malonate-derived polyconjugated esters. By taking advantage of the tight ion-pair control of organozinc(II)ates, it was possible to switch between 1,4- and 1,6-conjugate additions by introducing a terminal ethoxy moiety in the conjugation.
开发了区域选择性合成方法,用于将格氏试剂衍生的有机锌(II)的1,4-和1,6-共轭物添加到丙二酸酯衍生的多共轭酯中。通过利用有机锌(II)酸酯的紧密离子对控制,可以通过在共轭物中引入末端乙氧基部分来在1,4-和1,6-共轭物之间切换。
