Selective O-demethylation of the ortho methyl catecholate of N,N',N"-tris-(2,3dimethoxybenzeyl)-l,l,l-tris-(L-methioninemehyl)-ethane (2) has been accomplished by boron tribromide. The intramolecular nucleophilic attack of divalent sulphur on methyl enhance this cleavage, favours this selctivity and

In connection with other work, we desired to demethylate a brcminated aryl methyl ether. which also contained an acid-sensitive group elsewhere in the molecule. The common acidic reagents (1,2) were obviously not applicable and, because Grignard reagents are of limited use in the presence of halog
