Topsentin alkaloids and their derivatives were designed, synthesized, and characterized on the basis of NMR and mass spectroscopy. The antiviral activities against tobacco mosaic virus (TMV) and anti-phytopathogenic fungus activities of these alkaloids were evaluated for the first time. Alkaloids 1c, 1e, 2b, and 2d displayed significantly higher antiviral activities against TMV than Ribavirin, emerging

Topsentins and related bis-indole alkaloids may be efficiently synthesized through an addition/oxidation sequence leading to 2-(3-indolylcarbonyl)-imidazole derivatives followed by a Pd-catalyzed heteroarylation with the appropriate 3-stannylindoles.

The total syntheses of three marinebis-indolealkaloids (1, 2, 4) of the topsentin family together with the synthesis of the unnatural deoxybromotopsentin (33) are described. Key elements include, a 1,2-addition-oxidation sequence to construct the bis-heteroarylketones (18, 19, 29, 30) and a Pd-catalyzed heteroarylation involving the 3-stannylindoles (12, 26)
