Solid-Phase Synthesis of Dinucleoside and Nucleoside-Carbohydrate Phosphodiesters and Thiophosphodiesters
摘要:
Unprotected nucleosides (ROH) were reacted with two polymers bound to N, N-diisopropylamino- 1,3,2-oxathiaphospholane in the presence of 1H-terazole. Oxidation with tertbutyl hydroperoxide or sulfurization with Beaucage's reagent, followed by the 1,3,2-oxathiaphospholane ring opening with unprotected nucleosides or carbohydrates (R'OH) in the presence of DBU, afforded nucleoside-(5'-5')-nucleoside or nucleoside- carbohydrate phosphodiester and thiophosphodiester derivatives through the elimination of polymer-bound ethylene episulfide. This strategy offers the advantages of facile isolation of final products and monosubstitution of unprotected nucleosides and carbohydrates.

A first aspect of the present invention provides a method of producing a liquid composition comprising stabilised particles of active species in oil by precipitating a solution of the active species in a non-solvent in the presence of one or more stabilisers, mixing the precipitate suspension with an oil and then removing the solvents. Further aspects of the present invention relate to liquid compositions produced by said method and methods of use of such liquid compositions.
