Hy&o~-5-iodo-2J-dimdimethoxyd-methylbenzoic acid (1) and 5-bromo-4-hydroxy-2,3-dimethoxy-6-methylbenzoic acid (2) are the polysubstituted aromatic carboxylic aciakfoundin calichemicin antibiotics.' The title compounds are synthesized on preparative scale from readily available methyl 4-0-bensylorsel
So far one has only succeded in synthetising 5.7~dihydroxy-6-methoxyflavonea bearing not more than one substituent on the phenyl side Aain /B-ring/ l-9. b tried to solve this problem by alkaline ring isomerization 10-12.
