Synthesis of renierone, 7-methyoxy-1,6-dimethyl-5,8-dihydroisoquinoline-5,8-dione and N-formyl-1,2-dihydrorenierone, antimicrobial metabolites from a marine sponge, Reniera sp.
Three isoquinolinequinone antimicrobial metabolites, renierone (3), 7-methoxy-1, 6-dimethyl-5, 8-dihydroisoquinoline-5, 8-dione (4) and N-formyl-1, 2-dihydrorenierone (6), isolated from a marine sponge (Reniera sp.), were synthesized.
