Cu/Pd‐Catalyzed One‐Pot Synthesis of 2‐(1,2,3‐Triazolyl)methyl‐3‐alkynylImidazo[1,2‐
a
]pyridines Involving Sequential SN Reaction/[3+2] Cycloaddition/Sonogashira Coupling Reactions
Based on the regioselective intermolecular Suzuki coupling and subsequent intramolecular Ullmann coupling reactions, one-pot synthesis of benzo[4,5]thieno[3,2-b]benzofurans (BTBFs) has been developed.
Pd(ii)–Ag(i) catalysed, highly efficient synthesis of diindolylmethanes under mild reaction conditions, with six new bonds being formed in a one-pot fashion, and the products being transformed into synthetically useful compounds.
