Twenty-two new dlhydroxamic acids havlng the general formula (CH,),[CON(R)OHL ( n = 2, 3, 4, 6, 8; R = H,

have syntheslred by condensation Of the acid chlorides with suitable aryihydroxyiamlnes or by the reaction of the esters with hydroxylamine and and Infrared' ""' and by elementai proton NMR spectra. 0021-9568/84/1729-0345$01.50/0

032, India The importance of hydroxamic acids, RCON(R')OH, in both biology and medicine is now well recognized ( 7 - 4 ) , and much of their biological activity seems to be related to their ability to chelate iron specifically ( 7 , 2 , 4). The trihydroxamic acid desferrioxamine B is currently being used for the treatment of iron overload disease (5, 6) and is usually given as the methanesulfonate salt under the trademark Desferal of the CibaGeigy Corp. Rhodotorulic acid, a dihydroxamic acid, has also
