Facile and selective procedure for the synthesis of bridged 1,2,4,5-tetraoxanes; strong acids as cosolvents and catalysts for addition of hydrogen peroxide to beta-diketones.

Journal of Organic Chemistry, 2009
A facile, experimentally simple, and selective method was developed for the synthesis of bridged 1,2,4,5-tetraoxanes based on the reaction of hydrogen peroxide with beta-diketones catalyzed by strong acids (H(2)SO(4), HClO(4), HBF(4), or BF(3)).

Second generation analogues of RKA182: synthetic tetraoxanes with outstanding in vitro and in vivo antimalarial activities

, 2011
A series of polar dispiro-1,2,4,5-tetraoxanes have been designed and synthesized by parallel synthesis. From this series, endoperoxides with activity as low as 0.2 nM have been obtained and representatives of this group have excellent oral activities in ...

Steroidal geminal dihydroperoxides and 1,2,4,5-tetraoxanes: Structure determination and their antimalarial activity

Steroids, 1996
Cholestane-derived gem-dihydroperoxides and tetraoxanes were synthesized starting from 5 alpha- and 5 beta-cholestan-3-ones by acid-catalyzed addition of hydrogen peroxide to the ketone. They were characterized by IR, NMR, and mass spectroscopy analysis aided by molecular mechanics calculations, and, in the instance of 5 beta-cholestane-3 alpha,3 beta ...
