DOI: 10.1002/ajoc.201600631
Abstract: A milder, more regioselective and practical approach to C3 or O-alkylation reaction of 4-hydroxycoumarins has been established. Both 2H-[3,2-c] furocoumarins and 4-hydroxycoumarin vinyl ether derivatives could be efficiently prepared by alkylating 4-hydroxycoumarins with electron-deficient allenoates… read more here.
