  • Publication number: 20080161563
    Abstract: The present invention relates to methods of reducing ketal acids, salts and esters to form corresponding ketal alcohols. More particularly, the reducing methods convert the ketal acids, salts, or esters to ketal alcohols by using a reducing agent that comprises a hydride that comprises one or more alkoxy moieties. The ketal alcohol is prepared in a hydrophobic reagent. This is purified by washing the hydrophobic reagent with one or more water washes. Because the ketal alcohol has some water solubility, the water washes are back-extracted with a hydrophobic solvent to recover additional ketal alcohol from such one or more water washes. The alcohol products are useful in many applications such as intermediates in the synthesis of pharmacologically important molecules.

  • Publication number: 20040186168
    Abstract: A means and method for treating malaria, schistosomiasis, and cancer using a spiro or dispiro 1,2,4-trioxolane is described. The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl on the other side of the trioxolane group, whereby the spirocyclohexyl ring is preferably substituted at the 4-position. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites.
