概要

• 論文の詳細を見る

• The coumarin isolated from Ariemisia 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.
