应用
2,3-Dihydrofuran is a versatile reagent used in lanthanide-catalyzed Diels-Alder reactions with 2-pyrones and in Rh(II)-stabilized cycloadditions with vinylcarbenoids. It is applied for alkylation by active methylene compounds, catalyzed by trans-Dichlorobis(triphenyl?-phosphine)?-palladium(II). It is also used in the preparation of biologically active compounds such as antitumor agents.

备注
