Herein, we present a novel C(sp3)–C(sp3) bond-forming protocol via the reductive coupling of abundant tertiary amides with organozinc reagents prepared in situ from their corresponding alkyl halides. Using a multistep fully automated flow protocol, this reaction could be used for both library synthesis and target molecule synthesis on the gram-scale starting from bench-stable reagents. Additionally
在此,我们提出了一种新颖的 C(sp 3 )–C(sp 3 ) 键形成方案,通过丰富的叔酰胺与由相应的烷基卤化物原位制备的有机锌试剂进行还原偶联。使用多步全自动流程方案,该反应可用于从实验室稳定试剂开始的克级文库合成和目标分子合成。此外,优异的化学选择性和官能团耐受性使其成为药物分子后期多样化的理想选择。
