developed for asymmetric Suzuki–Miyaura couplings of challenging heterocyclic substrates. Computer modeling pointed to a tunable, yet unexplored quadrant in BI‐DIME, leading to the discovery of the 3′,5′‐dimethyl‐substituted ligand which improved the atropisomeric selectivity of the Suzuki–Miyaura reaction from the previously reported 5:1 dr to 15:1 dr for the synthesis of a challenging HIV integrase intermediate
通过计算机指导的方法,针对具有挑战性的杂环底物的不对称Suzuki-Miyaura偶联设计并开发了新的单膦配体系列。计算机模型指出BI-DIME中有一个可调的但尚未探索的象限,从而导致发现了3',5'-二甲基取代的配体,该配体从先前报道的5:1 dr改善了Suzuki-Miyaura反应的阻转异构体选择性。15:1博士用于合成具有挑战性的HIV整合酶中间体,而其他各种喹啉底物则可达到24:1博士。
