Article abstract of DOI:10.1248/cpb.40.1770

The coumarin isolated from Artemisia carvifolia Wall was proved synthetically to be 7,8-dimethoxycoumarin and not 5,8-dimethoxycoumarin as previously proposed. 3,4-Dimethoxy- and 3,6-dimethoxysalicylaldehydes gave the corresponding coumarins in good yield by the method using phosphorane reagent in N,N-diethylaniline under reflux.
