- 論文の詳細を見る
A mixed Ullmann reaction of methyl 3-iodo-(Xb) and 5-iodo-2,4-dimethoxybenzoate (XIb) gave dimethyl 2,4', 6,6'-tetramethoxy-3,3'-biphenyldicarboxylate (VI), m.p. 164〜166°. It was proved to be identical with an ester (IIIb) which was derived from matsukazelactone (I). Consequently, matsukaze-lactone was represented by formula (Ic), 7,7'-dimethoxy-6,8'-bicoumarin and its biogenesis undoubtedly involves oxidative coupling.
