TRICYCLIC ORGANIC MONOPEROXIDES AND METHOD FOR PREPARING THEM Russian patent published in 2012 - IPC C07D493/18 

FIELD: medicine, pharmaceutics.

SUBSTANCE: present invention refers to chemistry of organic peroxides, ketone derivatives, more specifically to a new class of tricyclic organic mononperoxides of general formula I: wherein R₁ = alkyl or 4-methoxyphenyl; R₂ = hydrogen, benzyl, unsubstituted or substituted alkyl with the substitutes presented by CN or COOR₃, wherein R₃ = alkyl, and to a method for preparing them consisting in a reaction of β,δ-triketones of general formula II: wherein R₁ and R₂ have the values specified above, and hydrogen peroxide in the presence of boron trifluoride in a medium of diethyl ester. The prepared compounds contain one O-O fragment, one acetal and two monoperoxideacetal fragments. They can find application as initiators for radical polymerisation of unsaturated monomers, as well as in medicine and pharmacology as antiparasitic agents.

EFFECT: preparing the compounds which can find application as initiators for radical polymerisation of unsaturated monomers, as well as in medicine and pharmacology as antiparasitic agents.
