C sp2 -c sp3 coupling
WebApplication of C sp2-C sp3 couplings on “drug-like” molecules. Late-stage functionalization on small molecule drugs, i.e. deuterium labelled drugs, especially CD 3 based molecules, and drug molecules with cyclopropane fragment, are prominent in pharmaceuticals (Scheme 2).

WebSep 9, 2016 · The attractive field of iterative cross-coupling has seen numerous advances, although almost exclusively in the union of sp2-hybridized partners. Conspicuously absent from this useful synthetic … 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.
