Applications of Triphenylpyrylium Salt-sensitized Electron Transfer Photo-oxygenation Reactions to the Synthesis of Aryl-substituted 1,2-Dioxanes as New Antimalarial Cyclic Peroxides

Autor: Kamata, Masaki, Tanaka, Takehito, Kanri, Kanae, Namai, Naoko, Hayakawa, Jun, Kim, Hye-Sook

Publikováno v: 新潟大学教育学部研究紀要自然科学編. 14(1):21-35

Triphenylpyrylium tetrafluoroborate-sensitized electron transfer photo-oxygenation was found to be an effective method for the transformation of arylethenes to 1,2-dioxanes. In vitro evaluation of the 1,2-dioxanes showed high antimalarial activity.
