this reagent alcohols are converted to the corresponding carbonyl compounds. With 1,2-dioles CCbondcleavage occurs. Decarboxylation of α-hydroxy acids proceeds quantitatively. Also thiols are converted to disulfides, hydroxy phenols to quinones, benzylamines to carbonyl compounds, tertiaryamines to the N-oxides, phosphines to phosphine oxides, sulfides to sulfoxides, and anthracene and phenanthrene

Camptothecin-based compounds are useful for treating a neoplasm in mammalian subjects by administering such compound to the subjects in combination with radiotherapy, i.e., the treatment of tumors with radioactive substances or radiation from a source external to the subject. Camptothecin-based compounds are modified by positioning at least one electron-affinic group around the camptothecin structure to enhance their value in combination with radiotherapy. New Camptothecin-based compounds are disclosed that are useful for treating cancer by administering the novel compounds alone or in combination with radiotherapy.
Electrochemical oxidation of catechols (1a—c) has been studied in the presence of 2-hydroxy-1,4-naphtoquinone (3b) in aqueous solutions, using cyclic voltammetry and controlled-potential coulometry. The results indicated that the electrochemically generated o-benzoquinones (2a—c) participate in Michael addition reaction with 3b to the corresponding benzofuranoquinones (8a—c, 10a—c). The electrochemical synthesis of these compounds has been successfully preformed at a carbon rod electrode with good yields using an environmentally friendly method.
