O-12-Acetyl-O-4,O-9-dimethylstealthin A mino-5-hydroxy-4,9-dimethoxybe
nzo[b]fluoren-10-one and O-4,O-9-dimethylstealthin C oxy-4,9-dimethoxy
-2-methylbenzo[b]fluoren-10-one), methylated derivatives of potent rad
ical scavengers produced by Streptomyces viridochromogenes, have been
synthesized using Suzuki coupling as a key step.
