The article was titled 《Stereoselective Synthesis of cis-2-Ene-1,4-diones via Aerobic Oxidation of Substituted Furans Catalyzed by ABNO/HNO3》, and you may find the article in Journal of Organic Chemistry.Synthetic Route of C20H14O The information in the text is summarized as follows:
A highly efficient and selective catalytic system, ABNO (9-azabicyclo-[3.3.1]nonane N-oxyl)/HNO3, for the aerobic oxidation of substituted furans to cis-2-ene-1,4-diones under mild reaction conditions using oxygen as the oxidant was reported. The catalyst system was amenable to various substituted (mono-, di-, and tri-) furans and tolerates diverse functional groups, including cyano, nitro, naphthyl, ketone, ester, heterocycle, and even formyl groups. Based on the control and 18O-labeling experiments, the possible mechanism of the oxidation was proposed. The experimental process involved the reaction of 1,3-Diphenylisobenzofuran(cas: 5471-63-6Synthetic Route of C20H14O)
1,3-Diphenylisobenzofuran(cas: 5471-63-6) can be used as a fluorescent probe for detection of superoxide anion radical (O2−) inside the membrane lipid layer by DPBF fluorescence quenching method. 1,3-Diphenylisobenzofuran(DPBF) can be used to study the single crystal molecular structure and solution photophysical properties of DPBF.Synthetic Route of C20H14O
