专利号:US-5442065-A 优先权日:1993-09-09 标 题:Synthesis of tetrahydroquinoline enediyne core analogs of dynemicin 发明人:MAGNUS PHILIP D; ILIADIS THEODORE; EISENBEIS SHANE A; FAIRHURST ROBIN A 权利人:UNIV TEXAS 摘要:A process is described for the preparation of the core azobicyclo[7.3.1]tridecaenediyne moiety of the antitumor antibiotic dynemicin. The synthesis allows efficient production of the enediyne as a stable, compound in good yield from the adamantyl N-protected azabicyclo[7.3.1]tridecadiyne. The adamantyl protecting group is employed in the starting material, N-adamantyl dihydroquinoline or N-adamantyl 6-methoxy quinoline. Also disclosed are process for the synthesis of 3-hydroxy-6-methoxyquinoline and several N-substituted derivatives of azobicyclo[7.3.1]tridecaenediyne. Solid tumor and leukemia assays were performed on the analogs of dynemicin. The results suggest a method that these compounds will useful in treating certain types of leukemias and solid tumors. The disclosed synthesis provides a route to new dynemicin intermediates and analogs which will allow development of second and third generation dynemicins.
