Lewis‐Acid‐Mediated One‐Pot Tandem Reactions for Synthesis of Structurally Diverse Furo[3,2‐c]coumarins

Abstract A concise, one‐pot route for the synthesis of furo[3,2‐c]‐coumarins under the catalysis of Zn(OTf) 2 is reported. Utilizing this synthetic strategy, libraries of furocoumarin analogues can be easily obtained by multicomponent tandem reactions with different nucleophile in the presence of 4‐hydroxycoumarin and arylglyoxal monohydrate system, This transformation exhibited highly atom economical and good functional group compatibility.
