bisphosphorylation cascade cycloisomerization of readily accessible γ-hydroxyl ynones and diphenylphosphine oxides is described. This strategy provides a variety of valuable polysubstituted bisphosphorylated dihydrofuran scaffolds via the construction of two C–P bonds and one C–O bond within a single procedure. This developed reaction system demonstrates good functional group compatibilities with considerably low
