我们发展了一种镍催化的不对称1,3-二取代烯丙基新戊酸酯与芳基环硼氧烷的交叉偶联反应。该反应的成功依赖于使用BnPPh 2作为镍(0)催化剂的支撑配体和NaOMe作为碱。该方法在烯丙基新戊酸酯和芳基环硼氧烷中显示出优异的官能团耐受性和宽范围,使得能够以高收率制备具有优异水平的区域选择性和立体化学保真度的1,3-二芳基烯丙基产物。
We have developed an enantiospecific, nickel-catalyzed cross-coupling of unsymmetric 1,3-disubstituted allylic pivalates with arylboroxines. The success of this reaction relies on the use of BnPPh2 as a supporting ligand for the nickel(0) catalyst and NaOMe as a base. This method shows excellent functional group tolerance and broad scope in both the allylic pivalate and arylboroxine, enabling the preparation of 1,3-diaryl allylic products in high yields with excellent levels of regioselectivity and stereochemical fidelity.
