The present disclosure relates to a novel method for preparing an arylnaphthalene lignan compound. In synthesis of arylnaphthalene lignan compounds and derivatives according to the present disclosure, a naphthalene backbone may be constructed first and an aryl group may be introduced at the final stage. Through this, various kinds of derivatives that could not be prepared from the existing methods can be synthesized effectively. Further, the synthesis method according to the present disclosure is appropriate for large-scale production.

Oxygenation of alkenes is one of the most straightforward routes for the construction of carbonyl compounds. Wacker oxidation provides a broadly useful strategy to convert the mineral oil into higher value-added carbonyl chemicals. However, the conventional Wacker chemistry remains problematic, such as the poor activity for internal alkenes, the lack of anti-Markovnikov regioselectivity, and the high

an arylnaphthalene lignan scaffold in high yields is presented. It involves a sequential intramolecular electrophilic attack of carbonyl on arylalkyne followed by benzannulation catalyzed by gold salt. AuCl3 in combination with AgSbF6 works better to effect this transformation. Selected products have been converted into arylnaphthalene lactone natural products such as justicidin E, taiwanin C, and
