Sequential alkylation of Hagemann's ester with methyl and
methallyl halides has been studied. Treatment of Hagemann's ester
with methyl iodide and sodium ethoxide gave a mixture of 21 and 25
in a ratio of 4:1. Alkylation of 21 with methallyl chloride and potassium
t-butoxide afforded a mixture of 37 and...
Glutathione, a ubiquitous intracellular tripeptide, protects cells by reacting with electrophiles and radicals that can damage cellular macromolecules. However, glutathione conjugation is now recognized as one mechanism by which drugs and xenobiotics can also be converted to reactive intermediates having toxic consequences to cells. The halogenated alkane 1,2-dichloroethane forms S-(2-chloroethyl)...
