Antimalarial Spiro-Bridged 1,2-Dioxolanes via Intramolecular Addition of Peroxycarbenium Ions to C-C Double Bonds
摘要:
Several 1,2-dioxolanes embedded in a rigid spiro-bridge framework fused with a built-in UV chromophore were synthesized through intramolecular [3+2] addition of in situ generated peroxycarbenium ions to C-C double bonds.
A Broadly Applicable Mild Method for the Synthesis of gem-Diperoxides from Corresponding Ketones or 1,3-Dioxolanes
摘要:
Ketones or ketals were readily converted into the corresponding gem-dihydroperoxides in high yields by treatment with ethereal H2O2 at ambient temperature in the presence of 2-5 mol % of phosphomolybdic acid.
