WebSep 9, 2016 · Introduction Iterative cross-coupling strategies in the presence of reactive handles for the rapid assembly of multifunctionalized small molecules have seen numerous advances in recent years, 1 capitalizing on decades of increasingly reliable C(sp 2)–C(sp 2) cross-coupling approaches.Arenes and heteroarenes constitute the core structural … WebAbstract. We describe the first one-pot borylation/Suzuki–Miyaura sp 2 –sp 3 cross-coupling between readily available aryl (pseudo)halides and activated alkyl chlorides. This method streamlines the synthesis of diaryl methanes, α-aryl carbonyls and allyl aryl compounds, substructures that are commonly found in life changing drug molecules.
