Abstract Two new lignans named J 1 and J 2 have been isolated from leaves of Justicia hyssopifolia , the latter as a β- d -glucoside, together with the known lignans helioxanthin, justicidin E, gadain, cubebin and sesamin. The structures of the novel compounds have been elucidated by spectroscopical methods and chemical transformations.

arylnaphthalene lactonelignans have demonstrated a variety of valuable medicinal chemistry properties and have therefore been of continued interest to drug discovery research. Our group has demonstrated a silver-catalyzed one-pot synthesis of the arylnaphthalene lactone core using carbon dioxide, phenylpropargyl chloride, and phenylacetylene. This new approach has been employed in the synthesis of six arylnaphthalene

2-dihydronaphthalene lignans is described. The method makes use of the classic Stobbe condensation followed by regioselective reactions that provide access to both the common and retrolactone lignans, e.g., 2 and 3. A total of 25 compounds, many of which are known natural products, were prepared and their antiviralactivity against human cytomegalovirus measured.Key words: lignan, Stobbe, arylnaphthalene
