Abstract
Methyl substituted 3-hydroxypyridin-4(1H)-ones have been synthesized. The pKa values and Fe3+ affinity constants of these ligands were studied. The introduction of an electron-donating methyl group at a different position of pyridinone ring markedly influences the pKa values of 3-hydroxy and 4-oxo groups. The pFe3+ values were also affected and are in the range of 17.6–20.7. The findings can be used to guide a design of 3-hydroxypyridin-4-ones with desirable pKa and pFe3+ values.

Abstract
A novel preparation of 5-functionalised pyridine derivatives is reported from 5-bromo-4-tosyloxypyridines via a Br/Mg exchange procedure with i-PrMgCl·LiCl, followed by addition of an electrophile. The reaction was carried out under mild conditions and gave good to high yields. The resulting 5-functionalised pyridine derivatives enrich the library of pyridinone-type iron-chelator prodrugs.
