Hydrobenzofurans are abundant in bioactive molecules, natural products and drug molecules. Transition-metal- catalyzed intramolecular or intermolecular C—H bond functionalization/cyclization cascade of O-linkered cyclohexadienone-tethered 1,6-enynes is an economic and efficient way to construct this skeleton. The progress in the synthesis of hydrobenzofurans from cyclohexadienone-tethered 1,6-enynes via C—H bond functionalization/cyclization cascade catalyzed by different transition-metals is discussed. The relevant reaction modes, mechanisms and the selection of ligands for chiral control are mainly introduced. Finally, the challenges and development prospects in this field are also prospected and discussed.
Key words: O-cyclohexadienone-tethered 1,6-enyne, cyclization reaction, C—H bond functionalization, hydrobenzofuran
