Oxidative Addition of 4-Hydroxycoumarin to Alkenes. An Expeditious Entry to 2,3-Dihydro-4H-furo-[3,2-c][1]benzopyran-4-ones1
摘要:
In the presence of one-electron metal oxidants (CAN, MAH), 4-hydroxycoumarin (1) adds to alkenes to give 2,3-dihydro-4H-furo[3,2-c][1]benzopyran-4-ones.
AN ALKOXY RADICAL REARRANGEMENT OF PHOTOCYCLOADDUCT OF 4-HYDROXYCOUMARIN AND DIMETHYLBUT-2-ENE TO FUROCOUMARIN AND FUROBENZO-γ-pyrone. Coumarin–BENZO-γ-PYRONE TRANSFORMATION

The alkoxy radical generated from a fused cyclobutanol obtained by the photocycloaddition of 4-hydroxycoumarin and dimethylbut-2-ene rearranges to a furocoumarin and a furo-benzo-γ-pyrone. The results afford further insight regarding the mechanism of the formation of the furocoumarins.
