Several series of pyrazino[2,1-b]isoquinoline and 6,15-iminoisoquino[3,2-b]-3- benzazocine compounds related to marine antitumour natural products are being synthesized and their in vitro cytotoxic activities are being evaluated against three human cancer cell lines. The key synthetic step is based on the synthesis of pyrazinoisoquinoline- 1,4-diones by the one-pot N-alkylation-cyclization of 3-arylmethylpiperazine- 2,5-dioxosilyllactims with aldehyde dimethyl acetals or through different á-amidoalkylation reactions and intramolecular cyclizations of Pictet- Spengler type. Pyrazino[2,1-b]isoquinolines, pyrazino[2,1,6-bc]isoquinolines, 6,15- iminoisoquino[3,2-b]-3-benzazocines and other more complex octacyclic compounds have been obtained an...
