Synthesis of Lipophilic 3-Hydroxy-2-methyl-4-pyridinone Derivatives

Hydrophilic 2- hydroxy-3-methyl-4-pyridinone derivatives were acylated with either long chain acid chlorides or with 1,3,5-benzenetricarbonyl trichloride. The products are either partially lipophilic, bidentatate or hexadentate chelators that form strong 3:1 and 1:1 complexes, respectively, with Fe (III).
