synthesis of the potent anti-HIV investigational treatment islatravir is described. The key step in this synthesis is a highly enantioselective catalytic asymmetric alkynylation of a ketone. This reaction is a rare example of the asymmetric addition of an alkyne nucleophile to a ketone through ligand-accelerated catalysis that was performed on a greater than 100 g scale. By leveraging a multienzyme cascade
描述了有效的抗HIV研究治疗药物Islatravir的合成。该合成的关键步骤是酮的高度对映选择性催化不对称炔基化反应。该反应是通过大于100 g规模的
配体加速催化将
炔烃亲核试剂不对称加成至酮的罕见例子。通过利用多酶级联反应,高度非对映选择性的羟醛糖基化可通过八个步骤完成。
