Applications · 3 items

Uses2,3-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.

Uses2,3-Dihydrofuran is a dehydration product of tetrahydrofuran (THF). 2,3-Dihydrofuran is also used in the preparation of niologically active compounds such as antitumor agents.

General DescriptionThe enantioselective Heck arylation of 2,3-dihydrofuran with aryl iodides was studied.
