A Highly Concise and Convergent Synthesis of HCV Polymerase Inhibitor Deleobuvir (BI 207127): Application of a One-Pot Borylation–Suzuki Coupling Reaction
摘要:
A highly concise and convergent synthesis of HCV polymerase inhibitor Deleobuvir (BI 207127, 1) was achieved, featuring efficient Pd-catalyzed one-pot borylation-Suzuki coupling where TFP was identified as the unique ligand effective for these transformations.
