Synthesis of two isoquinolinequinone antibiotics, 7-methoxy-1, 6-dimethyl-5, 8-dihydroisoquinoline-5, 8-dione (3) and N-formyl-1, 2-dihydrorenierone (4), isolated from a marine sponge Reniera sp., are described.
Chemistry of renieramycins. Part 6: Transformation of renieramycin M into jorumycin and renieramycin J including oxidative degradation products, mimosamycin, renierone, and renierol acetate
The transformation of remeramycin M (1m) into renieramycin J (1j) and jorumycin (2) is presented along with the results of antiproliferative assay data. The chemical stability and the oxidative degradation of 2 and renieramycm E (1e) to generate simple isoquinoline alkaloids, such as mimosamycin (7), renierol acetate (12), and renierone (8) are also described.
