The reaction of methyl mercaptoacetate (5) with phenyl-p-benzoquinone (6) or 5-p-benzoquinonyl-3',5'-di-O-acetyl-2'-deoxyuridine (10) resulted in the formation of the three possible adducts to the quinone rings of 6 and 10; an additional product in the reaction with 10 was the unsubstituted hydroquinone (14). Both reactions were found to be solvent dependent; in buffered aqueous acetonitrile the meta

The title compound (1), designed as a suicide inhibitor of thymidylatesynthetase, can be prepared by silver(II) oxide oxidative demethylation of the corresponding dimethoxyphenyl derivative. Compound 1 shows time-dependent inactivation of thymidylatesynthetase (methotrexate-resistant Lactobacillus casei) and saturation kinetics, and the inactivation is responsive to substrate protection. The inactivation
