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(triphenylphosphine)palladium(II). It is also used in the preparation of biologically active compounds such as antitumor agents.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Aplicaciones
El 2,3-Dihidrofurano es un reactivo versátil utilizado en reacciones de Diels-Alder catalizadas mediante lantanidos con 2-pironas y en cicloadiciones estabilizadas con Rh(II) con vinilcarbonoides. Se aplica para la alquilación mediante compuestos activos de metileno, catalizados por trans-diclorobis(trifenilfosfina)paladio(II). También se utiliza en la preparación de compuestos biológicamente activos, como los agentes antitumorales.
