A five-step synthesis of aaptamine, a marine alkaloid containing a benzonaphthyridine ring, from 6,7-dimethoxy-8-nitro-1(2H)-isoquinolone was accomplished in satisfactory yield.As a basis for the above synthesis, a facile preparation of 6,7-dimethoxy-1(2H)-isoquinolones from 3,4-dimethoxybenzaldehydes was developed using the palladium-catalyzed reaction of o-bromobenzaldehyde derivatives with trimethylsilylacetylene as a key reaction.Keywords-synthesis; aaptamine; palladium-catalyzed reaction; trimethylsilylacetylene; 6,7-dimethoxy-1(2H)-isoquinolone
